I using the same settings as i do for 0.72 and previous versions but on 0.73 i dont have as much free covnentional memory

on 0.72 i have 623k free
on 0.73 i have 372k free

my mem settings are
xms=true
ems=true
umb=max

everything i load in the autoexec area is loaded with lh, since the mem command on dosbox doesnt seem to allow listing of memory usage i cant see what is actually using the memory

Memory and Autoexec Area from 0.72

Use a default dosbox config file then change entries bit by bit so you see
which one eats up 300+k of memory.

i REM'd SET PATH=%PATH%;%DOS32A%;C:\DOS\EXTRA\CTMOUSE;c:\DOS\EXTRA\SDD;C:\DOS;C:\DOS\EXTRA\Batch;C:\DOS\EXTRA\Batch\Games;C:\DOS\EXTRA\ULTRASND\WINDOWS;C:\Windows;C:\DOS\EXTRA;C:\GAMES\X-COM\TRAINER\;C:\DOS\EXTRA\DPMI

and the memory went up to 633

by removing %path%; it went up to 504k

so they must have stopped loading that into uppermem it would seem

i'll shorten it as much as possible till its fixed, thanks

on closer inspection it's %DOS32A% being added to path that seems to be taking up most of the mem butfor soem reason if i remove that i cant run msd to see free mem, i shall do some more investigating

Ok after further testing it appears that more than 8 paths in set path causes low memory and with 9 some things dont load that are in paths in set path which is strange but the latter doesnt happen with 10+ just the low mem problem

well we could run out of environment space.
As those are close positioned around the memory control blocks we might overwrite them.
