Sb: #TRAPV exception error

mike, OSK errors 1XX are generated by an unused vector #XX. Exception Vector #7
is defined as TRAPV. TRAPV is the instruction for "Trap on Overflow".
Therefore :
1) An Overflow condition is causing the exception and this condition was
anticipated by the C generated code(hence the TRAPV instruction).
2) The lack of an exception handling routine causes the error.
If you understand the code or what to do on an overflow, you could install your
own handler, if not, you could simply try installing an RTI into vector #7.
There may even be a handler routine in one of the C-libs or CIO? If you wish to
determine where the exception is coming from, you could install a routine into
vector #7 to read the stacked address and display it.
Hope this helps. Also if what you need beta tested could run on Atari ST/OSK I
would be glad to help.
