Assembly Language Anyone?

Hey folks,

I'm working on a program in assembly code for Sim8086 and I need to manipulate an entered string to make it upper-case.

Does anybody have any experience with this?

Thanks

Is your string ascii encoded? If so isn't it just a case of starting at the start of your string (first memory address) and looping through taking 32 off each byte until you reach the end (null terminator?).

Yeah this how I would do it as well.

You'll need to check that each byte is in the lower case range (97-123) before modifying it as well.
