I am converting a dll used by Visual Basic 6 from Powerstation FORTRAN to CVF 6.6. After fixing the comment lines, the dll compiled & linked ok. But when I make the first function call in VB I get "Out of stack space". I used dumpbin and it looks like all the procs/funcs are there. The old dll works fine. I have not programmed in FTN for several years and can't help but think that I am probably missing something simple (I hope). I did set the /stack:0x80000000 but it did not help. Any ideas?
