Red screen of death on old DOS accounting software (corrupted background structure)
I need help tracing down the source of this error i'm getting.
I'm guessing somebody who was doing c++ in the DOS era could of seen it allready,
Maybe it is not an OS error but application error colored red.

I would be grateful if somebody could answer me the following:

 - what exactly is corrupted background structure error
 - where could i find a manual for fm_rd , fm_ed .. and other listed
    stack funcs (are those functions at all ?) ? I'm hopping knowing
    what they are will help me locate the exact moment the error
    triggers.

**All the info I have that could possibbly help:**

 - it's an old single core Pentium (error popped on AMD machine also and
   others) w ATA disk.
 - I presume it's coded in c++
 - uses Paradox DB
 - occures at the moment I try to print out some accounting data and save changes to disk(DB).(it's acctually 2 operations in one so im
   not sure which one errors out)
 - nothing prints , nothing saves to DB
 - FAT filesystem

I'll update in the morning if I find anything in the machines logs.

Thank you all very much in advance!!
