The Use of Number Sign Symbol # ?

[letminho]

Hi,

Im looking at an old code that uses that seemingly uses the # number sign symbol but I cannot figure out what its function is and it does not seem to exist on the internet.

For example, A = X#Y is something close to what I am seeing.

Could be be an old language/syntax that is no longer being used? I am relatively new to SAS and not familar if there was even an old syntax.

I really need to know as soon as possible, THANKS

Without seeing more code or possibly some input / output of the result the following is a complete guess:

Font change

It may be that the original code was stored in a different font, possibly on a mainframe, and when transferred to another system the font encoding didn't quite work.

In a longer shot, if the code is old enough or from some shop then the # could have been an Editor directive which would behave somewhat like a SAS macro but was used in an editor external to SAS.

If the place in the code looks like exponentiation was involved then it may have been a ^.

If the code with # involves Input or Put statements then the # is used to indicate either the line to read from or column to print to but would not normally occur in calculations.

What is the context? What procedure is being run?   In PROC IML (formerly PROC MATRIX if we are going back to the '80s), the # operator denotes elementwise multiplication. See the article "Ways to multiply in the SAS/IML language."

I believe this is what is happening in my program! Thank you so much Rick!
