X+1; Why?

chimanbj — Mon, 04 Apr 2011 19:59:48 GMT

A colleague of mine is wondering how the syntax:

x+1;

works. It obviously produces the same result as:

x=x+1;

but she wants to understand why.

Thanks!

Review the topic of how a SAS DATA step performs a "retain" or doesn't, depending on the statement syntax and/or whether you have coded a RETAIN statement.

This didn't sufficiently address the question of why this works.

Go to the online doc and search "sum statement syntax"
