How to obtain a letter of NC program name in post-processing

[Genericxg]

How to obtain a letter in the NC program name by judging a statement or script. For example,

I want to get the letter marked (S) in the picture.

This is the judgment of obtaining the last letter of the name

%p(NC Program Name)%.substring(%p(NC Program Name)%.length-1,%p(NC Program Name)%.length).toUpperCase() == "M"
What should I do to get the middle letter S

[Jonathan_Artiss19]

What are the other variables? Or does the name only have an S or no S in it?

[Genericxg]

Yes.

The name has S.
