Hello Jose, >>The XMS swap feature means: Copy most of FreeCOM to XMS while a program >>is running, and mark the memory as free.

Don't them ? no. they only way to have a small memory footprint when executing programs is HIMEM+XMSSWAP or CALL /S > If not, do you know why ? someone 'forgot' to implement it tom ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
