I give up, where does this question come from?
Why would anyone want to know what assembler op codes are the "most important"?

Hello and welcome to the forums icon_smile.gif

Is there some relationship to a CA product with your question?

Simply said, the most important instructions are the ones you need to code in order to implement a requirement or those that are already in use in some code you are executing.

If that is not what you are looking for, please clarify.

I'll also move this from the CA forum unless there is a reason to have it here.

Hello,

Either by looking in source libraries at your site or by doing a web search for sample assembler code you can evaluate which are "most" common.

There will be a difference between business application code and system support code. From my experience, there are many, many common instructions. There are some seldom used instructions and macros, but even those are too numerous to list here.

If you want to learn assembler from ground zero, i'd recomend going to the Murach publishing web site and buy a copy of the assembler book written by Kevin McQuillen. It will be a good investment.
