@INTRODUCTION
The RAG Software GRAM User Menu System,
GUMS, extends the cartridge menu
concept of the TI 99/4A to provide a
user built menu of disk based programs.
GUMS provides you with fast menu access
to all your favorite programs on disk,
and provides you with a convenient menu
driven file and disk maintenance
package.
You must have a fully expanded system
including a GRAM device. GUMS was
built and tested on:
.sp;in+5
PGRAM+ Card from Horizon,
GRAM KRACKER from Miller's Graphics,
.sp;in+0
it should also work on:
.SP;IN+5
PGRAM Card from Horizon,
GRAMULATOR from CaDD Electronics.
.sp;in+0
These devices have one feature in
common, that is, each GRAM block is 8K
bytes. All TI cartridges use only 6K
GROMS. This leaves 2K bytes in each
GRAM block unused, for a total of 10K
bytes of unused GRAM. GUMS uses these
2K blocks. This means that GUMS can
share your GRAM device with almost any
other cartridge. GUMS has some special
features when it is sharing the GRAMS
with TI Extended BASIC. It also has
special features for the multi level
GRAMS of the PGRAM+ Card.

@FAIRWARE
This package is a FAIRWARE release,
please feel free to copy it and
distribute it to your friends. Make
sure each copy you make is complete.
Fairware contributions of $10 can be
made to:

@GUMS^OPERATION
GUMS makes use of the builtin
capabilities of the TI 99/4A GROM
Operating System to take control of the
system on power up or reset. GUMS
bypasses the usual colour bar screen
and presents its main selection menu
immediately. The GUMS menu has four
selections of its own plus all the
usual entries for the cartridge that
GUMS is sharing the GRAM device with.
For example, if GUMS is loaded with
Extended BASIC, the main menu would be
as shown below.
.sp;in+5
A^^PROGRAM LIBRARY
B^^UTILITY LIBRARY
C^^FILE MAINTENANCE
D^^DISK MAINTENANCE
E^^TI BASIC
F^^TI EXTENDED BASIC
.SP;IN+0
If your GRAM device is a PGRAM+ Card
the main menu will have entries for all
the cartridges loaded into all four
levels of GRAM.
The "Program Library" and "Utility
Library" are the items that provide you
with easy access to your disk based
programs. Selecting either of these
entries will present you with another
selection menu of up to 13 of your
programs. Building these menus is
described later. You provide the text
to be displayed on the menu and the
device/filename of the program to be
loaded and run when the item is
selected.
Your programs may be E/A Option 5 type
programs or may be TI Extended BASIC
programs. If the program is XB then
GUMS must be sharing the GRAM device
with XB.
The "File Maintenance" and "Disk
Maintenance" items provide you with a
convenient disk manager that uses only
operations defined by the disk ROM. It
should work for all compatible disk
controller cards and for most RAM
disks.
Each of these four sub-menus have the
following selections displayed at the
bottom of the screen.
.sp;in+5
1^^RUN E/A OPTION 5
2^^RUN E/A OPTION 5 (XB ENV)
3^^RUN XB PROGRAM
.SP;IN+0
Selecting one of these will cause GUMS
to prompt you for the filename of the
program to be run. Item 2 is the same
as item 1 except for the VDP setup.
Item 2 is provided because some popular
E/A programs are designed to be run
from the Extended BASIC environment.

@GETTING^STARTED
First, make a working copy of the GUMS
distribution disk. Make sure the
distribution disk has a write protect
tab and use it &only to make working
copies.
In this manual it is assumed that you
know how to use your GRAM device and
the software provided with it.
If your GRAM device is the PGRAM+ Card,
you must load GUMS into page 1.
The use of GUMS is quite intuitive, so
at this point you might like to load it
all up and try it out. Just follow the
steps below.
.sp;lm+5;in-3
1.^Load your favorite saved cartridge
into the GRAM device.
2.^Load file "GUMS" into the GRAM
device on top of your cartridge.
3.^If the saved cartridge you loaded in
step 1 was TI Extended BASIC, then load
file "GUMS/XB" on top of all the
previous stuff.
4.^Now load the GRAM device dependent
code: file "GUMS/PG" for the PGRAM or
PGRAM+ Card, or "GUMS/GK" for the GRAM
KRACKER. This code gives you entry A
on the Utilities Menu.
5.^Try it out by restarting the system.
6.^Save the GRAM device to disk, this
is your GUMS saved cartridge.
.SP;LM-5;IN+0
Now, if you had fun in step 5 above,
you can study the rest of this manual,
especially the section on how to add
your programs to the Program and
Utility menus, and to tailor other
values in GUMS to your configuration.
.sp2;cp5
@GUMS^MENUS
All of the menus presented by GUMS are
similar and follow the usual TI
programming standards. The items in
the menus have letters rather than
numbers because there may be more than
nine entries. A menu item is selected
by touching the corresponding key with
Alpha Lock either on or off. Pressing
BACK (FCTN 9) takes you to the previous
level menu. Pressing QUIT (FCTN =)
resets the system and begins again with
the main menu.
Note that if, during a system reset,
the space bar is pressed and held, GUMS
will exit to the normal TI colour bar
and first level menu.
.sp2;cp5
@GUMS^DATA^ENTRY
During input to any of the GUMS
provided routines, the function keys
all work in their usual way. In
particular,
.sp;lm+25;in-20
FCTN 1 ^INS^^^^^^^^^Insert Character
FCTN 2 ^DEL^^^^^^^^^Delete Character
FCTN 3 ^ERASE^^^^^^^Erase to end of
field
FCTN 4 ^CLEAR^^^^^^^Erace entire field
FCTN 5 ^BEGIN^^^^^^^Begin again at first
field
FCTN 6 ^PROC'D^^^^^^Begin execution with
all data as is
FCTN 7 ^AID^^^^^^^^^***
FCTN 8 ^REDO^^^^^^^^Same as BEGIN
FCTN 9 ^BACK^^^^^^^^Go back to previous
level menu
FCTN = ^QUIT^^^^^^^^Reset system
^^^^^^^^ENTER^^^^^^^Enter data for this
field and continue with next field, or
if this was the last field, execute
function
FCTN S ^Left^Arrow^^Move cursor left
FCTN D ^Right^Arrow^Move cursor right
FCTN X ^Down^Arrow^^Same as ENTER
FCTN E ^Up^Arrow^^^^Go to previous
field
.lm-25;in+0;sp
When single character inputs, such as
"menu selections", "disk numbers" or
"Yes/No" are expected then touching the
single key is sufficient and ENTER need
not be pressed.
Where possible, previous inputs are
retained and are presented for
modification when a similar input is
required. This is especially true in
the file and disk maintenance sections.
You can move between the four GUMS
selection menus, Program Library,
Utility Library, File Maintenance and
Disk Maintenance, by pressing Up or
Down Arrow. This is especially useful
between the File and Disk Maintenance
menus as inputs will be retained
between menus using this method.
.sp2;cp5
@TAILORING^GUMS
There are four areas of GUMS that must
be tailored to your environment.
.sp;in+3
1.^The Library and Utility Menus
2.^The printer filename
3.^The printer setup values
4.^The file/disk values
.sp;in+0
You can make your modifications using
either program RAGPATCH (on the
distribution disk) or using the GRAM
memory editor supplied with your GRAM
device.
The advantage of using RAGPATCH is that
you have a record of your modifications
in a file and can easily change and
reapply them. A patch file, GUMS/STD,
is supplied on the distribution disk
which you can modify to suit your
needs. The values in GUMS/STD are
those which are already in the
distributed version of GUMS.
&Tailoring^GUMS^Menus
There are two identical GUMS menus in
GRAM: the Program Library menu
beginning at GRAM address >9814, and
the Utility Library menu beginning at
GRAM address >9A30. Remember that the
first entry in the Utility Library may
already be used if you have loaded
GUMS/PG or GUMS/GK.
Each menu entry is 40 bytes (hex >28)
long. The entry contains:
.sp;in+5
^1 byte^^-^entry type
19 bytes^-^menu text
20 bytes^-^filename of program
.sp;in+0
The types of entries are:
.sp;in+5
blank^-^unused entry
^^E^^^-^E/A Option 5 program, VDP as
per E/A
^^X^^^-^E/A Option 5 program, VDP as
per XB
^^G^^^-^E/A Option 5 program, VDP as
per GPL
^^B^^^-^Extended BASIC program
^^I^^^-^Internal GPL program
.sp;in+0
The type for an E/A Option 5 program
can be selected by trying E, X or G and
see how the program reacts. A garbled
screen is an indication that the
program wants a different type.
For a type I entry, the filename area
contains a 2 byte GRAM address of the
GPL program and a 2 byte "GRAM read
data address". The "GRAM read data
addresses" are >9800, >9804, >9808 and
>980C for the four pages of GRAM in the
PGRAM+ Card. The other GRAM devices
have only one page of GRAM with "read
data address" of >9800.
Below is a map of both menus.
.lm+5;sp;ai
Menu Program Menu Utility Menu
Item Address Address
----- -------------- --------------
A >9814 >9A30
B >983C >9A58
C >9864 >9A80
D >988C >9AA8
E >98B4 >9AD0
F >98DC >9AF8
G >9904 >9B20
H >992C >9B48
I >9954 >9B70
J >997C >9B98
K >99A4 >9BC0
L >99CC >9BE8
M >99F4 >9C10
.FI;LM-5;SP
&Printer^Name
The printer name begins at GRAM address
>7809. Its format is:
.sp;in+5
^1^byte^^-^name length
28^bytes^-^printer name
.sp;in+0;sp
&Printer^Setup^Values
The printer setup values, used by
"Printer Setup" of the "File
Maintenance" menu are located beginning
at GRAM address >F800. Each entry is 3
bytes. Entries shorter than 3 bytes
should be padded with >00. The entries
are in the same order as the menu
items.
.sp;in+5
>F800^^Select Elite Mode
>F803^^Select Pica Mode
>F806^^Condensed Printing On
>F809^^Condensed Printing Off
>F80C^^Expanded Printing On
>F80F^^Expanded Printing Off
>F812^^Emphasized Printing On
>F815^^Emphasized Printing Off
>F818^^Double Strike On
>F81B^^Double Strike Off
>F81E^^Select 8 lines per inch
>F821^^Select 6 lines per inch
>F824^^Select Skip over Perforation
>F827^^Form Feed
.sp;in+0
The printer setup values in the
distributed system are for a STAR
NX1000 printer.
&File/Disk^Values
The values for file and disk
maintenance are located beginning at
GRAM address >F82A (immediately
following the printer setup values).
The values are:
.sp;lm+5;ai
Address Length Function
------- ------ ---------------
>F82A 15 FROM default
>F839 15 TO default
>F848 1 Sides on disk,
S=single, D=double
>F849 1 Disk density,
S=single, D=double
>F84A 3 Print margin
>F84D 3 Print lines per page
>F850 1 Print line numbers,
Y=yes, N=no
.fi;lm-5;sp2;cp5
@FILE^AND^DISK^MAINTENANCE
Most of the file/disk maintenance
operations are fairly obvious, only a
few items need extra explaination.
In "Copy File" a "to" filename of
asterisk means use the "from" filename.
In "Selective Copy" and "Selective
Delete" the entire disk catalog is read
at the beginning. As the file names
are presented,
.sp;in+5
ENTER^^^^^^-^means do the operation
Up^Arrow^^^-^means go back to the
previous file
Down^Arrow^-^means skip to the next
file
.in+0;sp
"Box Format" assigns disk names in
sequence. It reads the "Sides" and the
"Density" and then it loops awaiting
entry of a disk number. You can flip
from disk to disk, using all your
drives. This allows getting one drive
ready while another is formatting.
.sp2;cp5
@PROGRAMMING^NOTES
TI Extended BASIC does not use the GRAM
block at >E000. GUMS uses the 2K
beginning at >F800. This leaves 6K of
GRAM that could be used by some other
GPL program.
For those interested in programming in
GPL, RAG Software produces two fairware
products to help you. A GPL Macro
Assembler and a GPL Disassembler. Both
of these packages come with a GPL
Language Manual on disk.
