Hi All,
I wrote a short program to show the contents of registers.
I placed it in a program called sandbox.asm to test out pieces of code and show register contents
at different points by calling ShowReg procedure.
I have found it helpful for a quick check to see if a piece of code is doing what I want.
Thought I would post it in case anyone is interested.
Best Regards
John
Works fine here John on Win 10 Professional. :t
Here is an alternative.

Hutch,
Thanks for the procedure, it will come in handy.
I am still working on learning all I can about masm32 assembly language.
I have learned a lot working on my editbyte program.
Hi John,
That is the best way to get up to pace, nothing beats writing enough code to get the swing of how it works. By the time you get up to pace we should have enough 64 bit stuff working to be useful.
Hi All,
Here is a new Version of sandbox program.
I use it when I want to see how a piece of code effects the registers.
Shows contents of registers in Hex, Decimal, Binary, and ASCII printable characters.
Updated version to show EBP & ESP registers and removed break down of EDI & ESI
Best Regards
John
