VP-Info Level 1 is the succesor to SR-Info version 3.14.
A number of new features have been added to VP-Info with this release.
The three most important are:
Support for memo fields.
You can now access memo fields from either dBASE III or dBASE 4.1
data files. As well, you can add memos to any of the VP-Info data
file types.
When viewing records in either BROWSE, EDIT, or READ, simply press
alt-R to read or view a memo, alt-W to change or write a memo.
Memos can also be accessed directly with the WRITE and TEXT commands.
Suppose you have a data file with a memo field called NOTES.
To print a memo (either to the screen, the printer, or to another file)
use the command TEXT M.NOTES.
To WRITE the same memo, enter the command WRITE M.NOTES.
Note that the WRITE commands invites you to save under a differant
name. You can thus load write with any of an ASCII file, a VP-Info
library block, or a memo, and save to any of the others.
The sample program MEMODEMO.PRG illustrates the use of memos.
Enhanced MENU( function.
The MENU( function has two new variations.
There is an optional third parameter, the timeout time in seconds.
For example, CHOICE=MENU(6,12,5) activates a menu with 6 choices,
a menu bar 12 characters wide, and a timeout in 5 seconds. If the
menu "times out", the result is set to 65 and your program can
respond accordingly.
The first parameter can be replaced by a string of first letter
triggers for each choice, including the zero choice.
For example, CHOICE=MENU("qrdn",12) might represent a menu with
3 choices (plus 0) where q means QUIT, r means REVISE, etc. Note
that the string is not case sensative - the user and the input
string are both converted to upper case before testing.
EDIT OFF
This command, formerly available only to VP-Info Professional, is
a programmer's delight! It allows you to create custom screens
using the TEXT command, define an ON FIELD structure, and have all
the EDIT keystrokes available to move from record to record as well
as append records.
Also:
The Info EFFECTS system.
This system provides for a variety of sound effects as well as
animated screen swapping.
To activate the system enter SET SOUND ON.
To de-activate the system enter SET SOUND OFF (the default setting).
There are a small number of hardware/software combinations that
confilict with the Info Effects.
Fifteen different sounds may be invoked by the command SOUND n where
n is a number from 0 to 15. Note that SOUND 2 is continuous. It can
be turned off by invoking another sound or by the command SOUND 0.
The screen effects all copy background screen 2 to screen 1, but
with animation. For example SCREEN Tear exposes the new screen
as though a page is torn from a pad. SCREEN Left slides the new
screen in from the left. The other variations are Right, Up, Down,
Open, and Close. Only the first letter of the variation is required.
i.e. SCREEN T is the same as SCREEN Tear.
