Hi friends,

The format of a variable is like this:

54361P(P)~U$

I want to delete (P)~U$ in this variable. i.e., I want “54361P” to be kept.

However, when I use code_new=compress(code,”(P)~U$”), the returned is “54361”.

I wonder, how can I get the outcome like “54361P”?

I think, the problem is that the compress function only compress specific characteristics. What I want to delete is the exact combination of characteristics, i.e., “”(P)~U$”.

Would you help me?

Thank you a lot!
