I'm trying to get an old Point Of Sale program running through Vdos. I can get the program to load the two main menus but when I attempt to load a site (so I can start a shift) I get "out of memory" errors. The old Help documentation points to a possible conventional memory issue or corrupted file or corrupted header.
I'm at a loss. Furthermore, my knowledge of how DOS works is fairly limited.
I can provide Vdos log file.
thanks if you can assist ...

I’m afraid the "out of memory" errors are only misleading, a catchall message when something goes wrong.
You could post the log file, though that doesn’t always help.

You use the Base edition of vDos, that isn’t supported.
First install vDos version 2019.05.01. Then create a ONQ directory, if you like C:\vDos\ONQ. Put the ONQ files in there, in autoexec I suppose:
CD ONQ
ONQY.EXE

Hi Jos, doing exactly the same thing as petfoodonly with ONQ but cannot find 2019.05.01 , I see some versions located at sourceforge.net/projects/vdos/files/ but not that one. Can you please advise where to get this version from? I am also getting out of memory errors when opening ONQ with the latest version of vDos. Thanks, Jason |

The advice then and now: First install/use the latest vDos version, now at 2020.03.01. The download location is also still: www.vdos.info/download.html. Jos |

Solved by direct contact.
ONQ tests for COMMAND.COM presence by opening that. No such file in vDos, it will satisfy applications looking for that by for instance the commonly used FINDFIRST DOS API call. Like a DIR COMMAND.COM will report it’s there. vDos doesn’t trap actually opening COMMAND.COM, so the solution was to create a text file with a line like “This is a fake COMMAND.COM to satisfy ONQ opening it”, and save it as COMMAND.COM to the ONQ directory.

Thank you that worked. It did not work if I put command.com in the onq folder - instead putting in the vdos directory I can now open a shift in Onq - thank you very much!
