Removing the suffix from a variable name

I have many variables all called something like A_YYY where YYY can be any combination of characters and numbers of different length. How do I automatically rename all of the variables as simply A to analyze in a loop?

By not creating them as separate variables:

I doubt that you wrote out all of those variable names by hand, which means you forgot to tell us the most important information: how did you get all of those variables into the workspace? That would be the best palce to fix this bad data design. For example, if they are loaded from a file then you should LOAD them into an output varaible:

S = load(...)

It's best to avoid that situation in the first place and make them as elements of an array when they're "created". See the FAQ:
