Hi all
Sorry for my unclearly writing - maybe because of my English.

I use asm51.exe as an assembler, like this:

asm51.exe xxx.asm

to create xxx.hex and then xxx.bin.

Under DOS, It's very easy, but It's different when I use the Shell function in VB6 uder Win2K environment, I don't know how to add "xxx.asm" into shell("asm51.exe",1). This is my problem.
