' WAT ?? Well, here's the deal. I usually use PBC to complile my Power
' Basic programs due to the file sizes involved, and edit them with
' the very fine shareware editor QEdit. QEdit can jump on load to
' a given file line -- but how could I get the error info from my
' screen to the command line (other than manually, of course) ??
' Well, PB can read the screen buffer just fine. But it took me a lot
' of tinkering to create ERFIND.BAS, to take that info off the screen,
' get the line #, make it into a batch file, and then stuff the
' keyboard buffer with the batch file's name so that when ERFIND is
' done, the batch file starts automatically !!
' USAGE: START WITH A BATCH FILE LIKE 'qp.bat'. THIS CALLS FIRST THE
' COMPILER, THEN IF ERRLEVEL > 0 ERFIND IS CALLED. THEN THE NEW
' BATCH FILE, CREATED ON THE FLY, STARTS THE PROCESS ALL OVER AGAIN.

Program Title: Add-Power Lib for PowerBASIC
Author Version: 2.7B
Author Registration: Donation.
Special Requirements: PowerBasic 2.10d+, 640K RAM, and a hard disk for s
Contains many useful, tested PowerBASIC routines. Write complete
pulldown menu interfaces, rodent-aware, just by modifying the demo
program. Fancy entry routines for string or numeric data, phone numbers,
dates, etc. (never use INPUT again!). Date arithmetic, get file dirs and
diskspace, open a data-entry window, dialog box, let users customize
colors, push and pop screens, and much more! All in PB units. In daily
use by author and others (posted on CompuServe) for as many as four
years.
