Select only 5 characters

[fg]

Hello, I wanted to know if it is possible to create a macro that makes me select only the first 5 characters of the name of the NC program. For example my program is called GG444_EXEMPLE_LAV and I want to select only GG444. It can be done?

Substrings:
The substring function returns part of the string. You can define where the substring starts and its length. The original string is unchanged.
The basic structure is:
string substring( string str, int start, int length)
For example:
PRINT = substring("Scooby doo", 2, 4)
The command window displays the result, ooby.
