Looks like that's a message related to trying to allocate beyond what is allowed in a variable - it appears to be a qbasic limitation, rather than dos, so I don't think increasing the memory allocated to dosbox will help.

I'm sure someone more familiar with qbasic in dosbox will be able to offer more help!

I should have included in my previous message that these programs work OK on older Windows systems -- Win98, XP, Vista, etc.

DOSBox is no "other windows system". Check that your app works fine under real dos first.

There are updated QBasic-compatible Windows-native Basic interpreters, if I'm not mistaken. Since you still have the BAS files, maybe they'd be worth a try. http://en.wikipedia.org/wiki/FreeBASIC comes to mind.

I've increased DOSbox's memory to 32 and 63 MB but still cannot run these executables. I even attempted to run the BAS files within QBasic but got the same error.

I use DOSBox under XP. I have a couple of utilities that I wrote in QBASIC. One of them runs in DOSBox just fine. (The other needs a printer.) I have never seen a string space error. QBASIC would not be able to use that much memory anyway.

Short of a
error 14
I do not know how I would get an error 14.

What do the programs do? What compilation options do you use?

The programs read in poorly-written HTML files, fix coding errors, eliminate deprecated code, create replacement XHTML files along with newly-created CSS files, and then upload them to the websites replacing the original files.
BTW, some lines in these original files are over 100,000 characters long!

Jorpho suggested I try other interpreters (thanks Jorpho) and I discovered that FreeBasic choked on a module that performed random inputs into a maximum sized string buffer -- but QBasic 71 was quite happy with this!

Discovering that, I decided to rewrite that module to use sequential I/O instead. I've just finished debugging the new module's code but haven't yet had time to try it within DOSbox. Hopefully things will work better this time.

Thanks for your helpful suggestions.
