echo off rem This patch originally suggested by a message on a Maryland junior BBS at rem 1(301)428-3145; automated batch file by John Wager. echo This program AUTOMATICALLY patches BASICA.COM. so that you can run it on echo an IBMPCjr without having a basic cartridge installed. It is also useful echo if you have a junior with more than 256K of memory; running cartridge echo basic with more memory than this requires special software. echo The main drawback of this patch is that it prevents you from entering echo commands in basic like RUN or LIST using the Function keys; you will have echo to type them in. The bottom ('key') line is also disabled. echo echo To make this patch, you will need to have copies on this disk of echo BASICA.COM from your DOS disk, DEBUG.COM from the supplemental DOS disk, echo and the file PATCH.TXT. If copies of these programs are not on this disk, echo press Fn B to stop this program and then copy them here. If copies of all echo of these files are already on this disk, pause for %%f in (BASICA.COM DEBUG.COM PATCH.TXT) do if not exist %%f goto end REN BASICA.COM BASICAJR.XOM DEBUG BASICAJR.XOM < PATCH.TXT REN BASICAJR.XOM BASICAJR.COM echo You should now have a version of BASICA.COM that will work on your junior echo just like it would on a full-size P.C., except that you will not be able echo to enter commands like RUN or LIST using the Function keys, and the last echo line of the screen will not have these Function keys labeled. Of course echo you will only be able to run programs written for the P.C.'s BASICA.COM echo rather than cartridge basic, but that is the price you pay. You can still echo run cartridge basic the way you normally would if you want to. echo echo From now on, to run BASICA type BASICAJR at DOS prompt. (If you try to run echo it with the name BASICA or BASIC, you will get a message that the BASIC echo cartridge must be installed, or it will jump to cartridge basic if it is echo installed. goto quit :end echo The necessary files are not on this disk; copy them here and try again. echo The files are BASICA.COM, DEBUG.COM, PATCH.TXT. :quit
