PBWindow.PBU version 2.10 has these features:
o For PowerBASIC 2.1 Power Pak. Another version is available
for PowerBASIC version 2.0x.
o Zoom windows. A procedure allows you to zoom windows onto
the screen.
o Tracking of all window attributes so when the window is
active, the window can be worked with, changed, and
restored to the original. This allows you to use the
window pointer (Wpt%) to reference any window and make
changes to it, if it is not overlaid by another window.
o Noise can be turned off, even if a window requests it.
o You can recolor a window instantly.
o By changing one variable in the Include file, you can
specify a minimum of 5 windows to a maximum limited by
memory and the size of your program. Since PowerBasic no
longer limits strings to 64k, and the windows are saved in
strings, PBWindow takes advantage of these new strings.
All inline routines were changed to a Object code in this
version. Some Functions are now built-in in PowerBasic.
o Ability to automatically make a menu selection.
o 12 Title area in a screen:
- Top Left
- Top Center
- Top Right
- Bottom Left
- Bottom Center
- Bottom Right
- Top Left Vertical Side
- Middle Left Vertical Side
- Lower Left Vertical Side
- Top Right Vertical Side
- Middle Right Vertical Side
- Lower Right Vertical Side
o Both vertical and horizontal centering within a box.

o 13 kinds of windows:
- Blank (no outline)
- Blank (no outline, no borders)
- Single line outline, top, bottom and sides
- Double line outline, top, bottom and sides
- Double Vertical line outline, single Horizontal
line outline

- Left transparent drop shadow
- Right transparent drop shadow
- Left light hatch drop shadow
- Right light hatch drop shadow
- Left medium hatch drop shadow
- Right medium hatch drop shadow
- Left heavy hatch drop shadow
- Right heavy hatch drop shadow
o Clear individual lines in a window
o Change attributes in a window on a line by line basis
o 5 kinds of menus
- No highlight
- The item is highlighted
- The item line is highlighted
- An arrow is used
- An arrow is used and the item is highlighted
o Restore a title outline after removing the title.

o Hercules and IBM Mono compatibility. While this was
developed for color enviroments, it works fine for a mono
mode.
o The ability to catch errors in writing programs by setting
a variable, UnderDevelopment%, to %True, and then disable
this by making it %False once your program is developed.
o Movement of all $Inline code to Object code.

2 What is PBWindow 2 What is PBWindow
PBWindow.PBU and PBWindow.INC allows you to add pop-up windows to
your PowerBasic programs. There are 22 Public routines in
PBWindow that you can access from your program:
1. FUNCTION GetAttribute 12. SUB PrtEOL
2. SUB GetForAndBack 13. SUB PrtEOLBox
3. SUB PrtBox 14. SUB NewBoxColor
4. SUB Rackett 15. SUB BuildMenu
5. SUB RemoveBox 16. SUB PrtAttrBox
6. SUB BoxTitle 17. SUB ClearBox
7. SUB MakeBox 18. SUB Recolor
8. SUB ZoomBox 19. SUB WriteScreenArea
9. SUB BoxScroll 20. SUB SaveScreenArea
10. SUB CtrBox 21. SUB PBWindowInit
11. SUB CtrAllBox 22. SUB ScreenInit
4 routines are in the PBWOBJ.OBJ file that by the nature of being
in the obj code are PUBLIC. They are :
1. SUB WritVidP
2. SUB ReadVidP
3. SUB Scroll
4. FUNCTION WhatCpu%
3 How to use PBWindow with your programs 3 How to use PBWindow with your programs
It is real easy to add PBWindow to your program. The only code
need to compile is:
$INCLUDE "PBWINDOW.INC"
near the start of your program. By near, we mean you may need
some metastatements in front of this, and a DEFINT A-Z, as the
unit uses this and the $Include expects this. You should set the
variable Max.Window% to some value greater than the default of 5
by placing the statement Max.Window% = nn where n is 5 or
greater. The demo uses 14. One Constant MUST be used. This is
%PBWSmall = 0 . For the registered versions, this means
something. For the non registered versions, this must be used for
the compile to work, but can be ignored otherwise. You may want
to add this to the INCLUDE file for simplicity. See the demo
source for other Constants. Also, the variable AutoBuildTime% may
1
be set. If not, it defaults to 30 seconds . A command line option
_________________________________________________________________
1. The demo starts out with this value, and then, if this value
is reached without a key being hit, it speeds up the showing
by using a 5 second delay.
Page 4 (c) 1987-90 Barry Erick Page 4 (c) 1987-90 Barry Erick
PBWindow DocumentationPBWindow Documentation
allows the overriding by specifying a value of 20 to 15000
seconds. To use this, start PWDemo like this: PWDemo /300 and
substitute the desired time for the 300. In the example, the time
delay will be 300 seconds. The two files needed to compile are
PBWindow.INC and PBWindow.PBU. The first file should reside in
your Include directory and the second in the Unit Source
directory. This will allow a compile to take place. However,
unless you add code to your program to make windows and use them,
the compiled code is useless. The steps are:
1. Place PBWindow.INC in your Include directory
2. Place PBWindow.PBU in your PBU directory
3. Place PBWObj.OBJ in your OBJ directory
4. Place the statement Max.Window% = nn where nn is the
maximum number of windows you need open at one time. 14 is
a good number, while 5 is the minimum and default if you
try to set it to a lesser number. Set the constant
%PBWSmall to 0. A typical statement would be:
Max.Window% = 14
%PBWSmall = 0
5. Place the $INCLUDE metastatement to your program to bring
in the PBWindow.INC file. If you have this in your INC
directory and have saved your configuration so PowerBasic
knows where to find files (see Options/Directories and
Options/Save in the PowerBasic manuals or menus or help).
A typical statement would be:
$INCLUDE "PBWindow.INC"
6. Make sure the file PBWOBJ.OBJ is in your current
directory, the PB Object directory, or your path, as this
file is necessary.You may then set the variable
UnderDevelopment% to %True to allow error checks on code
you send to the PBWindow.PBU file. Once done with the
development, you can either remove this code or make it
%False. It defaults to %False. To enable it, the statement
would be:
UnderDevelopment% = %True
and to disable it, you would either remove it or change it
to:
UnderDevelopment% = %False
7. The Include file sets the default variable type to be
integer, so if your program does not have a DEFINT or
other DEFxxx statement in it, the default variable type
will be Integer and not single precision. This is an
(c) 1987-90 Barry Erick Page 5 (c) 1987-90 Barry Erick Page 5
PBWindow DocumentationPBWindow Documentation
important point, if some routines no longer work when you
add PBWindows to them. It is perfectly safe to place a
DEFnnn statement after the $INCLUDE metastatement for the
rest of your program to default to your type. Note that
all calls to PBWindow routines require either Integer or
String variables and constants.
8. Add the various PBWindow statements to your program to add
the windows. Note that you have to Make A Box before you
can Print To A Box. A box is the same as a window, and may
be referenced to in either way in this documentation.
To compile the demo, simply load PWDemo.Bas into the IDE and
press Alt-F9 or F10/Compile/Compile. From the PBC, simply type
PBC PWDemo -CE. All command switching has been taken care of in
the program. Note that the demo expects to find DayDate.PBU and
PbWindow.PBU in either your default directory or PBUDestination
library. The object files, PBWObj.OBJ and CPU.Obj are expected in
your default library or PBObj library and PBWindow.INC in your
default or INClude directory. The files DayDate and CPU are only
used in the demo and are not needed to use PBWindow.PBU,
PBWObj.OBJ and PbWindow.INC. Details to the use of DayDate.PBU
and/or CPU.Obj are in the PWdemo.Bas source file. Additional
details may be in a file called Readme if necessary.
4 PBWindow Routines 4 PBWindow Routines
There are three main routines to PBWindows, MakeBox, ZoomBox and
RemoveBox. MakeBox or ZoomBox are the first procedures to call to
make a window, and RemoveBox is the last called, to remove the
window. The rest of the 22 routines support these two main
routines.
MakeBox This routine makes a box. Your limit on the MakeBox
maximum number of windows open at any time is set
with the Max.Window% variable. The calling
sequence is:
Call MakeBox(Wr%,Wc%,Wh%,Ww%,fc%,bc%,_
BoxKind%,Shadow%,Racket%,Bfc%,Bbc%)
Where:
Wr% WindowRow. The row on the screen Wr%
where the windows top row shall
be placed.
Wc% WindowColumn. The Column on the Wc%
screen where the windows left
side will be placed.
Page 6 (c) 1987-90 Barry Erick Page 6 (c) 1987-90 Barry Erick
PBWindow DocumentationPBWindow Documentation
Wh% WindowHeight. The number of rows Wh%
(not the row number) that the
height of the window will take.
This must be two more than the
number of rows you plan to place
within the window.
Ww% WindowWidth. The number of Ww%
columns (not the column number)
that the column will take.
fc% ForegroundColor. This is the fc%
color the text within the box
will take. See Table 1 for valid
numbers.
bc% BackgroundColor. This is the bc%
color the text within the box
will take as its background. See
table 1 for valid numbers.
BoxKind% This defines if there will be a BoxKind%
outline around the window. There
are 11 legal values:
0 = Blank (no outline)
1 = Single lines
2 = Double lines
3 = Double vert,
Single horiz
4 = Single vert,
Double horiz
5 = Single horiz, No vert
6 = Double horiz, No vert
7 = Solid border, all around
8 = Light Hatch, all around
9 = Medium Hatch, all around
10 = Heavy Hatch, all around
11 = Same as 5, with no
border
12 = Same as 6, with no
border
13 = Same as 0, with no
border

PBWindow DocumentationPBWindow Documentation
Shadow% This defines if you want a black Shadow%
drop shadow, and if so, if you
want that shadow to be
transparent. There are 11 Drop
Shadow types:
0 = None
1 = Left , solid
2 = Right , solid
3 = Left , transparent
4 = Right , transparent
5 = Left , Light Hatch
6 = Right , Light Hatch
7 = Left , Medium Hatch
8 = Right , Medium Hatch
9 = Left , Heavy Hatch
10 = Right , Heavy Hatch
Racket% Defines whether you want noise Racket%
when the window opens or closes.
There are 2 valid values:
0 = No Racket or Noise
1 = Racket or Noise
Bfc% BoxlineForegroundColor. This is Bfc%
the color the BoxKind line will
have if there is a boxline. For
it to be the same as Fc, use a
-1, otherwise all values for Fc
are valid for Bfc.
Bbc% BoxlineBackgroundColor. This is Bbc%
the color the BoxKind line
background will have if there is
a boxline. For it to be the same
as Bc, use a -1, otherwise all
values for Bc are valid for Bbc.
Note: If you have a shadow, do
not use 0 (or Black) for best
results.
Table 1: Colors for Fc,Bc,Bfc, and Bbc Table 1
0 Black (16) 8 Gray (24)
1 Blue (17) 9 LtBlue (25)

PBWindow DocumentationPBWindow Documentation
Note that the minimum and maximum values for Wr,
Wc, Wh, and Ww are dependent on the Shadow%
value. The screen positions are normally 1 thru
80 across and 1 thru 25 up and down. When a
shadow is involved, the bottom of the raster is
always 1 more than Wh, as the width is also one
greater than Ww specifies. If we are calling for
a left drop shadow, then the starting column is
actually one less than Wc, and so the minimum
value is 2. For a right drop shadow, the maximum
screen position is 79, as position 80 is taken by
the shadow.
ZoomBox This routine makes a window that grows in size as ZoomBox
it is made. Other than this, it is exactly the
same as MakeBox. Refer to MakeBox on page 4 for
details of the parameters.
Rackett This procedure makes a noise if the variable Rackett
NoNoise% is %True. If NoNoise% is %False, this
procedure then does nothing. The Calling sequence
is:
Call Rackett
RemoveBox This routine removes a opened window. It removes RemoveBox
the last opened window, and there are no
parameters to pass. The Calling sequence is:
Call RemoveBox
GetAttribute This function returns a integer attribute when GetAttribute
supplied with Forecolor and BackColor, as defined
in Table 1. Usage:
variable% = GetAttribute(ForeColor%,_
BackColor%)
GetForAndBack This procedure supplies the ForeColor and GetForAndBack
BackColor integers from a supplied integer
attribute. Calling sequence is:
Call GetForAndBack(attr%,forecolor%,_
backcolor%)
where forecolor and backcolor are as defined in
Table 1.
PrtBox This procedure prints a string within the PrtBox
currently (last) open window. A Call MakeBox()
must have first been made. Usage:
Call PrtBox(r1%,c1%,stuff$)
(c) 1987-90 Barry Erick Page 9 (c) 1987-90 Barry Erick Page 9
PBWindow DocumentationPBWindow Documentation
where:
o r1% = Row within the window, not screen.
First available row is 1, and is
referenced to Wr+1. The last row available
is Wh-1.
o c1% = Column within the window, not
screen. First available column is 1, and
is referenced to Wc+1. The last column is
Ww-1.
o Stuff$ = The string to print at the Fc and
Fc used when the window was made with
MakeBox.
BoxTitle This places a title on the border line of a box BoxTitle
already made with a call to MakeBox(). There are
12 places, and values, that can be passed. Usage
is:
Call BoxTitle(Where%,What$,Bxfc%,Bxbc%)
Where:
Where% Defines one of 12 places around Where%
the window box for the title to
be:
Table 2: Box Title LocationsTable 2
Horizontal Vertical
1 = Top Left 7 = Middle Left
2 = Top Middle 8 = Middle Right
3 = Top Right 9 = Top Left
4 = Bot Left 10 = Bot Left
5 = Bot Middle 11 = Top Right
6 = Bot Right 12 = Bot Right
What$ Is the Text to place Where. Make What$
sure it fits. If this is Null,
then the border is rebuilt. Also,
if first character of What$ =
chr$(234) (Ω), then the title
border location is rebuilt using
the new string.
Bxfc% Is the integer color What$ will Bxfc%
be. It may be any valid
foreground color as defined in
Table 1. It will be the same as
Bfc if made equal to -1.
Bxbc% Is the integer color the Bxbc%
background of What$ will be. It
Page 10 (c) 1987-90 Barry Erick Page 10 (c) 1987-90 Barry Erick
PBWindow DocumentationPBWindow Documentation
may be any valid background color
as in Table 1. It usually looks
best if it is the same as Bbc.
Making it equal to -1 will make
it equal to Bbc.
BoxScroll This scrolls the text within a window up or down BoxScroll
one row at a time at a specified color. This
allows you to scroll off text in one color, and
bring it back in another color. The entire window
is cleared by calling this routine the number of
rows there is in the window. The calling sequence
is:
Call BoxScroll(Direction%,Fcolor%,Bcolor%)
Where:
Direction% can be one of two values: Direction%
0 = Up one row
1 = Down one row
FColor% Is the color text will be on the FColor%
new row, if any is pulled to it,
which it usually isn't. Valid
FColors are the same as Fc in
Table 1. A value of -1 will make
it the same as Fc.
BColor% Is the color of the row BColor%
background that is scrolled in.
Valid BColors are the same as Bc,
as shown in Table 1. A value of
-1 will make it the same as Bc.
CtrBox This is the same as PrtBox, except it centers the CtrBox
text on the row within the window. The Calling
sequence is:
Call CtrBox(r1%,Stuff$)
Where:
r1% Is the row within the window to r1%
center the string Stuff$.
Stuff$ Is the text to center within the Stuff$
window at row r1. The color was
defined when the window was made
with MakeBox().
CtrAllBox This is similar to CtrBox, except it centers the CtrAllBox
text in the window, both vertically and
horizontal. The calling sequence is:
(c) 1987-90 Barry Erick Page 11 (c) 1987-90 Barry Erick Page 11
PBWindow DocumentationPBWindow Documentation
Call CtrAllBox(Which%,HowMany%,Stuff$)
Where:
Which% Is the number of HowMany this Which%
line of Stuff$ is.
HowMany% Is the Total Number of lines that HowMany%
are to be centered in the current
window.
Stuff$ Is the text to center within the Stuff$
window at Which line of HowMany
lines.
PrtEOL This does a erase to EndOfLine using the current PrtEOL
attribute of the window. The calling sequence is:
Call PrtEol(Row%,Column%)
Where:
Row% Is the row within the window, not Row%
screen. First available row is 1,
and is referenced to Wr+1. The
last row available is Wh-1.
Column% Is the column within the window, Column%
not screen. First available
column is 1, and is referenced to
Wc+1. The last column is Ww-1.
PrtEOLBox This prints a string within the window and then PrtEOLBox
does a EOL using the PrtEol procedure. The
calling sequence is:
Call PrtEOLBox(row%,column%,stry$)
Where:
Row% Is the row within the window, not Row%
screen. First available row is 1,
and is referenced to Wr+1. The
last row available is Wh-1.
Column% Is the column within the window, Column%
not screen. First available
column is 1, and is referenced to
Wc+1. The last column is Ww-1.
Stry$ Is the string to print. Stry$
NewBoxColor This procedure sets the saved attributes of the NewBoxColor
current window to your specified color. This will
Page 12 (c) 1987-90 Barry Erick Page 12 (c) 1987-90 Barry Erick
PBWindow DocumentationPBWindow Documentation
allow the next action within that window to be of
the new color. The calling sequence is:
Call NewBoxColor(frewe%,bvcxv%)
Where:
Frewe% Is the foreground color. Frewe%
Bvcxv% Is the background color. Bvcxv%
BuildMenu This procedure allows you to use the window BuildMenu
system for menus. Several types and actions are
provided. You can have a pointer to point to
items, a highlighted bar the width of the window,
or the width of the string. The first letter can
be highlighted. Selection can be made on all
types by moving the bar and hitting Enter, or by
hitting the highlighted first letter. Another
option allows you to hit the highlighted
character, and if there is more than one item
starting with that character, the next hit of the
same letter will select the next item, and this
will continue and wrap around to the first.
Selection is done with the Enter key or
automatically in this instance.
To use the feature, you must build a list of
items and assign them to the string array
mList$(). This array is DIMmed to 20. The last
item in the list must be either a null string
2
("") or the string "@#$" . This signals the end
of the list. For example:
MList$(1) = "One"
MList$(2) = "Two"
MList$(3) = "@#$" (or MList$(3)=""
Would signal to build a menu consisting of two
items. The calling sequence is:
CALL BuildMenu(mitem%,bmstart%,bmFirst%,_
bment%,bmffore%,bmback%,_
bmhfore%,bmhback%,bmbar%,_
Mlist$(),Auto%,PointerColor%)
Where:
mitem% Is the item number selected mitem%
within the menu.

PBWindow DocumentationPBWindow Documentation
bmstart% Is the item number to start with. bmstart%
This item will be the highlighted
or pointed to item. Normally this
is 1.
3
bmFirst% If True , this sets the first bmFirst%
letter in each menu item to be
highlighted, and selection by the
first character is allowed. If
False, then this is not possible.
bment% If True, this means the Enter key bment%
is required on first letter
selection. If False, then hitting
the highlighted first character
selects that item. Note that True
allows several items to share the
same first character, while
setting this false will require
all items to have a unique first
character.
bmffore% This is the foreground color to bmffore%
use for the first character
highlight. -1 means to use the
same as the box uses.
bmfback% This is the background color to bmfback%
use for the first character
highlight. -1 means to use the
same color as the box uses.
bmhfore% This is the foreground color for bmhfore%
the menu item when highlighted
with a bar. -1 means to use the
same color as the box.
bmhback% This is the background color for bmhback%
the menu item when highlighted
with a bar. -1 means to use the
same color as the box.

bmbar% This selects the type of bar: bmbar%
Table 3: Bars GeneratedTable 3
0 = No Highlight
1 = The Item is Highlighted
2 = The Box Width is Highlighted
3 = An Arrow is used
4 = An Arrow is used and the item

Mlist$() This is the list for the menu as Mlist$()
described above.
Auto% This variable, if %True, will Auto%
allow the menu to return the
current highlighted item as the
selection after a timeout, or by
the user, whichever occurs first.
If %False, the user must make the
selection. The variable,
AutoBuildTime% determines the
amount of time waiting. If this
routine times out, and is
returned automatically, Auto%
will return %True. If the user
hit a key to select an item, then
Auto% will return %False.
PointerColor% PointerColor% allows the pointer PointerColor%
or arrow, to be a different color
than the highlight. If this is
set to a -1, then the color of
the pointer will be the same as
the highlight defined by the
variable bmhfore%. This variable
must be passed even if you do not
use an option that specifies a
pointer.
Also, see the variables Bar0to2Off% and
Bar3or4Off% in Appendix A.0.
PrtAttrBox This prints a string within the current window PrtAttrBox
using a different attribute than the default, but
does not change the attributes for the window for
subsequent calls. The calling sequence is:
Call PrtAttrBox(Row%,Column%,String$,Fore%,_
Back%)

Where:
Fore% Is the foreground color to use. Fore%
If set to -1, the default
foreground color is used.
Back% Is the background color to use. Back%
If set to -1, the default
background color is used.
ReColor This allows you to recolor the last window. This ReColor
was designed to do this because it would be hard
to work a routine to recolor only the portion of
a window that another one isn't sitting on, which
can happen if we allowed recoloring of more than
the last window. The calling sequence is:
Call ReColor(Fore%,Back%,BorderFore%,_
BorderBack%)
Where:
Fore% Is the new foreground color to Fore%
use. If set to -1, the foreground
color will not change.
Back% Is the background color to use. Back%
If set to -1, the default
background color is used for no
Page 16 (c) 1987-90 Barry Erick Page 16 (c) 1987-90 Barry Erick
PBWindow DocumentationPBWindow Documentation
apparent change in the
background.
BorderFore% This carries the new border BorderFore%
foreground color. Again, if set
to -1, the color remains
unchanged.
BorderBack% As in the others, this holds the BorderBack%
new background color and if set
to -1 does not change.
WriteScreenArea This is called by MakeBox internally and really WriteScreenArea
should not be used externally. It is provided
here as a way to write to an area without keeping
track of what you are doing. When Remove box is
called after this, the previous window and this
one is removed. Not recommended to use, but the
usage is:
Call WriteScreenArea(UpperLeftRow%,_
UpperLeftCol%,_
NumOfRows%,NumOfCols%,_
Text$,Attrs$)
Where:
UpperLeftRow% is the upper left row number, 0 UpperLeftRow%
to 24
UpperLeftCol% is the upper left column of the UpperLeftCol%
box, 0 -79
NumOfCols% is the total number of columns NumOfCols%
from the UpperLeftCol.
Text$ is the text to write to the Text$
screen. The length of the string
is determined to be no greater
than NumOfCols, as this routine
is used to write not the entire
box, but one row of the box.
Attrs$ is the attribute to use and must Attrs$
equal the length of text$
SaveScreenArea This is also called by MakeBox internally and SaveScreenArea
should not be used without totally understanding
the code. It is made PUBLIC so some advanced uses
may be used externally of the program. Not
recommended to use, the usage is:
(c) 1987-90 Barry Erick Page 17 (c) 1987-90 Barry Erick Page 17
PBWindow DocumentationPBWindow Documentation
Call SaveScreenArea(UpperLeftRow%,_
UpplerLeftCol%,_
NumOfRows%,NumOfCols%,_
SaveText$,SaveAttr$)
where:
UpperLeftRow% is the upper left row number, 0 UpperLeftRow%
to 24
UpperLeftCol% is the upper left column of the UpperLeftCol%
box, 0 -79
NumOfCols% is the total number of columns NumOfCols%
from the UpperLeftCol.
SaveText$ is the text retrieved from the SaveText$
screen. The length of the string
is equal to NumOfCols, as this
routine is used to read not the
entire box, but one row of the
box.
SaveAttr$ is the attribute used on the SaveAttr$
screen and equals the length of
text$
PBWindowInit This routine is used by the $Include file. It PBWindowInit
returns the screen segment and the retrace mode.
It also Dims dynamically all arrays. If
RetraceMode% is 0 then we do no retrace on screen
writes, else we do check, for a slower display.
This happens in CGA modes. If you need to use
this just to see the routines, the calling
sequence is:
CALL PBWindowInit
Returned:
ScreenSegment% returns the ScreenSegmentscreen ScreenSegment%
segment of the adapter, either
&HB000 or &HB800.
RetraceMode% returns the retrace mode. If you RetraceMode%
have a cga adapter, then we use
retrace protection, and this will
return non zero. If zero, then
there is no wait for retrace, and
screen writes are much faster.
You can fool PBWindows into not
using retrace with your program
by using the statement Retrace% =
0 after the $Include statement in
your program.
Page 18 (c) 1987-90 Barry Erick Page 18 (c) 1987-90 Barry Erick
PBWindow DocumentationPBWindow Documentation
ScreenInit This sub returns the ScreenSegment and Retrace ScreenInit
mode, unlike PBWindowInit, which Dims many arrays
and should only be called once. This may be
called as often as you wish if you need to update
the current modes. The calling sequence is:
Call ScreenInit(ScreenSegment%,RetraceMode%)
Returned:
ScreenSegment% and RetraceMode%
See PbWindowInit for details.
ErrorChecker This sub is used internally, but is made Public ErrorChecker
for use within the registered PBWSmall version to
allow any optional pbu access to it. If you need
to use it, the calling sequence is:
Call ErrorChecker(ErrorMessage$,ErrorCode%)
Returned:
A window with the message and code
A prefix of PBWindow Error is
tacked onto it.
The Function/Sub name where the
call came from is shown.
WhatCPU This Function returns the cpu type as an integer. WhatCPU
4
For example :
Print "The CPU is a ";WhatCpu%
Note: %MaxWindow is no longer supported. This constant has been
changed to Max.Window%, an integer meant to be set in your
program to equal the maximum number of windows you will have open
at any one time. This must be used prior to invoking the $Include at any one time
metastatement. Also, the variable AutoBuildTime% should be set at
this time if you want something other than the default of 0. A
new Constant is introduced, which must, for the distributed
version, be set to 0. It is %PBWSmall.
Example:
AutoBuildTime% = 60 'set timeout to 60 seconds
Max.Window% = 14 'set a max of 14 windows at any one timeany one time
%PBWSmall = 0 'necessary constant that MUST be placed
' prior to the next statement or the
' program will not compile.
$Include "PBWindows"

5 The Demo PWDemo.Bas 5 The Demo PWDemo.Bas
The demo file does nothing but demonstrate the routines available
in PBWindow. This file is menu driven, the menu being one built
from the PBWINDOW unit. Following the instructions in section 3
on page 4 will show you how to compile this demo. Briefly, the
file, PWDemo.Bas goes to your \PB default directory, PBWindow.INC
to your \PB\INC directory, PBWObj.OBJ to your \PB\OBJ directory,
and PBWindow.PBU to your \PB\PBU directory. The demo has
directives in it to compile to .exe, turn off error tests, and to
turn off break tests. Also, Library routines are stripped, as
they are not needed for the demo. If you use the Command Line
Compiler (PBC.EXE), and you do not have a PBC.CFG (configuration)
file, you may place all the files in the same directory as your
PBC.EXE file and simply type PBC PWDEMO /CE to compile this, as
the demo program has metastatements in it to direct the compiler
as to its duties. One .PBU file, DayDate.PBU, is only used for
the demo and is not needed to use PBWindows.
When you run the demo, either you make the selections by
selecting and hitting enter on the main menu, and spacebar when
asked to, or do nothing. The demo will automatically run if the
users does nothing for 30 seconds. At that time, it changes to a
3 second timeout to make for a faster moving demo than if this
were left at 30 second.

is needed for commercial license terms. Also let us know what
program this will be used in. If this is included in a
commercial program, then an additional licence fee will be
invoked. Details for this licensing is available from the
author. If you find this program useful, but do not need the
source code, why not register as a way of saying thanks for the
routines? It would be greatly appreciated. Be sure to state
what disk format you want. This can be supplied on either 5 1/4
or 3.5 inch low density disks at no extra cost until further
notice. Please specift if you want the version for PowerBASIC

6.3 Update availability 6.3 Update availability
The .pbu file will need to be updated as new major versions of
PowerBasic become available, and possibly a minor upgrade will
require this, also. Therefore, the .pbu file will be made
available to users. If the .Obj file requires a update, it too
will be made available. This availability may mean electronic
distribution via CIS EasyPlex, or GEnie's GEMail, or it might
mean a disk will be sent to you. In any case, the new version
of the entire program will replace the current version. Contact
the author if you need upgrade information when newer versions
of PowerBasic are released.

Appendix AAppendix A
Public VariablesPublic Variables
These are the Public Variables in the file PBWindows. They may
be referenced to in other areas of the program, but should not
be altered nor reused for your own use.
Attrs%(MaxWindow%) Current attribute for which window. Attrs%(MaxWindow%)
AutoBuildTime% The time for the BuildMenu to wait AutoBuildTime%
for user input before automatically
making the selection. The parameter
Auto% in BuildMenu, must be %True
for this to mean anything. The
valid values of AutoBuildTime% are
1 to 15000 seconds. The demo limits
the values to 20 to 15000 seconds.
IsColr% If true, this system was in color IsColr%
when PBWindow started. This does
not limit PbWindows to color, but
lets you decide if color is
available. Use ScreenSegment to
decide if you even want to try
color. If ScreenSegment is &B000
then we do have Hercules or IBM
Mono mode, and color should not be
attempted. VidMode% may also be
looked at. If it is 7, then this is
a mono mode.
Bar0to2Off% This offset is added to the Bar0to2Off%
starting column specified by the
BmBar% variable when BmBar is < 3.
It is defaulted to 3. This is
active in Menu display only.
Bar3or4Off% Similar to Bar0to2Off%, this works Bar3or4Off%
for values of BmBar% being 3 or 4.
The default is 0, and this, too, is
only active in Menu display modes.
BoxBorderAttrs%(MaxWindow%) The attributes of the border for BoxBorderAttrs%(MaxWindow%)
each window.
(c) 1987-90 Barry Erick Page 25 (c) 1987-90 Barry Erick Page 25
PBWindow DocumentationPBWindow Documentation
BoxKinw%(MaxWindow%) Keeps the window kind for each BoxKinw%(MaxWindow%)
wpt%.
Max.Window% Variable carries the maximum number Max.Window%
of windows.
Mbc% MakeBoxBackgroundColor holds the Mbc%
last windows Background color.
Mbbc% MakeBoxBorderBackColor holds last Mbbc%
window's border background color
used.
Mbfc% MakeBoxBorderForeColor holds last Mbfc%
window's border foreground color.
Mfc% MakeBoxForegroundColor holds the Mfc%
foreground color of the last
window.
Noise%(MaxWindow%) Noise information for which window. Noise%(MaxWindow%)
Note: You can also control how a
window is removed by changing the
value in this array. Normally, a
window is removed with noise if
Racket was made when the window was
made, and vice versa. To make a
quiet removal of a noisy window,
set Noise(WindowNumber) = 0 and to
make it noisy, if the window was
quite, make Noise(WindowNumber) =
1.
ScreenSegment% This variable carries the video ScreenSegment%
segment address.
Shadows%(MaxWindow%) Shadow information for which Shadows%(MaxWindow%)
window.
RetraceMode% This variable is used to see if we RetraceMode%
need to check for snow. If VidMode%
= 7, then do NOT make this %True.
It will lock up a mono system. You
can force this off, by placing the
command, RetraceMode = 0 right
agter the $include PBwindow.Inc
statement in your program.
PBWc%(MaxWindow%) Window Column of which window. PBWc%(MaxWindow%)
PBWh%(MaxWindow%) Window height of which window. PBWh%(MaxWindow%)
Page 26 (c) 1987-90 Barry Erick Page 26 (c) 1987-90 Barry Erick
PBWindow DocumentationPBWindow Documentation
Wpt% Current window pointer, if 0, no Wpt%
windows are open.
PBWr%(MaxWindow%) WindowRow of which window. PBWr%(MaxWindow%)
PBWw%(MaxWindow%) Window Width of which window. PBWw%(MaxWindow%)
Mlist$(20) For carrying the items in a menu. Mlist$(20)
NoNoise% If 0, then racket or noise is NoNoise%
allowed through the various
routines. If other than 0, then
noise is not allowed, even if the
internal sub Rackett is called.
UnderDevelopment% This variable controls error UnderDevelopment%
checking while you develop your
program. It defaults to %False, but
you may set it in your program,
after the $include "PbWindow.Inc"
metastatement, to allow error
checks to be made in several area
of PBWindow.PBU. See the Appendix
Error Codes for details of the
errors.
VidMode% This returns the video mode the VidMode%
system was in when PbWindows was
initialized. The most common text
color mode is 3, and the mode to
look for is 7. If this is 7, then
we have a Hercules or IBM Monograph
adapter. If we do, then do not use
any colors and definitely do not
modify the variable RetraceMode%,
as that cannot be %true for a mono
system. It is best to leave
RetraceMode alone, anyway.

Error CodesError Codes
If the variable UnderDevelopment% is %True, error checking is
enabled to check the parameters you send to PBWindows. Along
with the name of the Function/Sub where is error is found,
these errors are printed in a window. The program will
terminate to allow you to correct the problem. Be sure to make
UnderDevelopment% %False once the program is debugged. Here are
the error codes in the program:
1 Starting Column must be > 0 From MakeBox or ZoomBox, 1 Starting Column must be > 0
you specified a starting
column less than 0.
2 Starting Column must be > 1 You specified a Left Drop 2 Starting Column must be > 1
Shadow and the starting
column is less than 2.
There must be room for a
shadow resulting in a
starting column >1.
3 Start Column + Width must be <=80 Since the screen width is 3 Start Column + Width must be <=80
80, you can't have a
wider window than the
screen width.
4 Start Column + Width must be < 80 You specified a right 4 Start Column + Width must be < 80
shadow, which requires
one more space than the
widnow width. The drop
starting position and the
width specified would
cause the display to go
off the current line.
5 Start Row must be => 0 You specified a starting 5 Start Row must be => 0
row above the screen by
specifying a row less
than 0.
6 Start Row must be <= 25 You specified a starting 6 Start Row must be <= 25
position at the end of
the screen.
(c) 1987-90 Barry Erick Page 29 (c) 1987-90 Barry Erick Page 29
PBWindow DocumentationPBWindow Documentation
7 Ending Row must be <= 26 You specified a starting 7 Ending Row must be <= 26
row and number of rows
that goes off the screen.
8 Ending Row must be <25 You are using a shadow, 8 Ending Row must be <25
which requires one row at
the bottom and specifed a
starting row and number
of rows, that when added
to the shadow row, would
take the image off the
screen.
9 Starting Column must be < 79 You specified a starting 9 Starting Column must be < 79
column at the rightmost
side of the screen.
10 No Windows Open You must call either 10 No Windows Open
MakeBox for Zoom Box to
open a window before you
can print in the window.
11 Too Many Windows Open You exceeded the 11 Too Many Windows Open
Max.Window% limit on the
number of open windows.
This defaults to 5 unless
you set this variable to
something else before the
$Include "PBWindow.Inc"
metastatement in your
program.

SHAREWARESHAREWARE
C.1 Definition of Shareware C.1 Definition of Shareware
Shareware distribution gives users a chance to try software
before buying it. If you try a Shareware program and continue
using it, you are expected to register. Individual programs
differ on details -- some request registration while others
require it, some specify a maximum trial period. With
registration, you get anything from the simple right to
continue using the software to an updated program with printed
manual.
Copyright laws apply to both Shareware and commercial software,
and the copyright holder retains all rights, with a few
specific exceptions as stated on page 23. Shareware authors are
accomplished programmers, just like commercial authors, and the
programs are of comparable quality. (In both cases, there are
good programs and bad ones!) The main difference is in the
method of distribution. The author specifically grants the
right to copy and distribute the software, either to all and
sundry or to a specific group. For example, some authors
require written permission before a commercial disk vendor may
copy their Shareware.
