Is it i need to run your CLSHEAP.PRG first ? or call your function inside the clsheap.prg?
And after that call my DLL function? (=G_OpenPort(@Chan1))

Can you tell me the step to proceed the DLL ?
Is it first :
1)declare the DLL
2)Call the function in CLSHEAP.PRG to converting numbers to various binary forms? Chan1 = CHR(8) + CHR(1) + NumToBININT(1) + NumToDWORD(5)
3)Call my DLL's function ? G_OpenPort(@Chan1)
Thanks.

regard,
