Subj : Re: PowerBASIC 3.5 for DOS To : Robert Wolfe From : Kevin Nunn Date : Wed Jun 28 2017 08:25 am I did find this https://www.pcorner.com/list/OS2/CFGINFO.ZIP/OS2CFG8.DAT/ If you search down for "If you need maximum memory", there is some info there on how to get up to 724k in a DOS session. Not sure if that'll work, but it's worth a try. And I'd suggest you make a separate "program" icon for this so you don't mess with your default DOS Session settings. And there are other old config.sys tips on that page that I used to use when I had minimal power/ram. Kev --- Telegard/2 v3.09.g2-sp4/mL * Origin: Razor's Domain/2 BBS (1:19/50.1) .
