Of course you can use the following structure:

Code:

var1=expression1:var2=expression2: ... etc

Then press CALC (which is removed from 991CW )

This is same as STO but without entry cancellation.

Check this video (How to emulate IF...THEN structure on CASIO fx-991EX):

Now I get why you are upset about the CALC function being gone. Casio sapped it's algorithmic power when the fx-991CW was released.

I wish we could store mutli-expressions in memory on Casio. There are some Sharp calculators (unfortunately not all), such as the EL-506TS, that has formula memory (F1-F4), I will see if I can store multi-expressions there.
