Something wrong with my Debug code?

[MaxEd]

I get garbage when use it under windows 2000. I can't figure out why! Any help would be greatly appreciated. Thank you!

Did you initialize ds?

What do the different external routines expect?

Do you have these routines? "Information has a tendency to be free. Which means someone will always tell you something you don't want to know."

AmKG,

I wrote this code and used MASM 6.1 (I think) to compile it. We're programming based on the Intel processor x86. I am new to assembly so I'm not sure what the external routines would expect. I thought that assmebly coding was prett standard for the Intel processor.

Assignment 1:
Find out what the 'CLEAR', 'NEWLINE', 'PAUSE', 'PUTDEC', and 'PUTSTRNG' need. At the very least, show their source code.

Assignment 2:
Did you, at any time, initialize the 'DS' register??? "Information has a tendency to be free. Which means someone will always tell you something you don't want to know."

I believe I did initalize it in the main moduel. The putstng and other things are part of an io.lib. I'm using masm 6.1

 

[AmkG]

Are the Io.lib functions documented anywhere? Maybe you are violating some rule that the Io.lib functions require to run properly. "Information has a tendency to be free. Which means someone will always tell you something you don't want to know."
