LINE25 Documentation
LINE25 is a BASIC aid program. It occupies less than 2.5K of RAM,
and boots only if there is a BASIC cartridge present. It must be used
with ATARI DOS II, and is configured for use with a 2-drive system.
After downloading LINE25.BIN, rename it AUTORUN.SYS and put it on
a DOS II diskette.
After booting, you will see a menu of the functions available with
LINE25. Most of these functions are self-explanatory, so only the
oddities will be covered here.
KEY - allows for direct use of the cursor keys, no need to
simultaneously press the CONTROL key. Use SYSTEM RESET to
restore normal functioning of the cursor keys.
FORMAT - requires that you enter FORMAT D1: (for example) to
activate the command. Entering FORMAT or FORMAT 1 will
result in the command being ignored. This is for your
safety.
START - the CONTROL-1 key sequence has been moved to the
START key. Pressing START once stops the listing, and a
second press restarts it.
SELECT - toggles the slow mode. This will slow down the
listing AND running of the program.
OPTION - toggles the superslow mode. It brings things to an
absolute crawl. Like SELECT, it affects both listing and
running speed.
The inverse video line at the top of the screen is a 25th line
(thus the name of the program), which displays information about the
amount of FREe memory remaining, the current line number being listed
or TRAced, and the number of the most recently read DATa statement.
By combining the effects of the console keys with the information
displayed in the 25th line, you can smash the little bugs that creep
into your masterpiece.
Pressing SYSTEM RESET will redisplay the menu that is on the
screen when the program first boots.
Some of the default parameters of LINE25 may be adjusted. See the
CUST25.BIN file (in an XA near you) for details.
Caveat!! We hogged the interrupts, so if you are being cute, try
another program, there is little room left for you.
If you want to escape from LINE25, enter DOS twice. The first
time will kill the program, and the second will get you to DOS.
Direct all obscure technical questions to Sysop*Richard
Brudzynski, I only helped write the program, I can't run it!
