Clipper 5.3 program under dosemu

Clipper 5.3 program under dosemu

[Bartos-Elekes Zsolt]

Hi!

I have to set up a dosemu environment for a clipper 5.3 program, using the 
DOS/16M dos extender. The problem is that the program can't use the memory 
above 1 MB. According to the docs, the program SHOULD use DPMI, and the logs 
show that it is actually doing some DPMI calls (GetFreeMem, Alloc, etc), but 
it is not using as much memory as DPMI offers.

Here are my memory settings:

$_xms = (16384)		# in Kbyte
$_ems = (off)		# in Kbyte (couldn't make the program use it)
$_ems_frame = (0xE000)
$_dpmi = (16384)	# in Kbyte
$_dosmem = (640)	# in Kbyte, <= 640

I have a simple Clipper program that displays the memory available to the 
program (251k gzippped), I can email to anyone willing to debug a little.

Other programs using DPMI (like Turbo Pascal 7.0's tpx.exe) are seeing and 
using correctly all DPMI memory available.

My system configuration:

Celeron 366, 128 MB RAM, ~100 MB swap
Debian 3.0r1
dosemu 1.1.5, compiled from sources

compiletime-settings:
config {
   experimental off
   sbemu off
   mitshm off
   vidmode off
   x off
   net off
   dodebug off
   linkstatic off
   cpuemu off
   aspi off
   svgalib off
   plugin_keyboard on
   plugin_kbd_unicode off
   plugin_extra_charsets off
   plugin_term off
   plugin_slang off
   plugin_translate off
   plugin_coopthreads on
   plugin_commands on
   plugin_demo off
   target_cpu auto
   prefix /usr/local
   bindir ${prefix}/bin
   sysconfdir /etc/dosemu
   datadir ${prefix}/share
   mandir ${prefix}/man
   docdir ${datadir}/doc/dosemu
   syshdimagedir /var/lib/dosemu
   x11fontdir ${datadir}/dosemu/Xfonts
   fdtarball none
}

Clipper version 5.3b Intl. (338)
DOS/16M version 6.01

Can anyone help me?

Thanks,
Zsolt

Actually I have access to the developer :-), but we will only be able to try 
it with blinker tomorrow morning.

Thanks,
