when I try to start Turbo Pascal 7.0 (TPX.exe, the protected mode version) in vDos 2016.06.01 I get a Illegal GRP4 Call x vDos Exception. x varies (seemigly correlated to the settings in config.txt). For some settings vDos just freezes without the message. TURBO.exe, the real mode version, can be started.
The protected mode IDE of TP doesn’t run in vDos. I don’t expect this will be fixed, TPX will be doing (I once assumed strictly) OS related and removed protected mode functions. So you would have to use the real mode IDE version of TP, or install DOSBox for program maintenance.

Thank you, Jos, for clarifying this. So no need for me to twiddle around with the settings. Will use TURBO.EXE instead of TPX.EXE for my trial of vDOS. I currently use DOSBox under Linux which has some issues for me (mostly compilation speed which is what I had back in the old DOS days...) and that's why I wanted to try vDOS.
Best regards,
Boris

config.txt contains
MOUSE=ON
FRAME=ON
WINDOW=20
LINS=50
COLS=80
Adding XMEM = 1 EMS does not help.
autoexec.txt only contains drive mappings like use x: x:\, and the path and prompt settings.
Your help would be appreciated to get TPX.exe to run.
Kind regards,
Boris
Should have mentioned that the host system is Windows 10 Professional 64bit in a VirtualBox virtual machine.
