I would write a function to remove blank characters in rename the string.  See attached.

We can turn my approach to a function where you can select the character to delete

Or we could also create a function to replace one character for another one (empty string means delete)

And here is a string trimmer using "search" and "substr" as you had tried to do

Note that this approach will not work OK if ORIGIN is set to a value different from zero AND the calculation option "ORIGIN in  Strings" is set (which is usually is not by default).

I think its easier to convert the string into a vector using "str2vec", trim all occurrences of spaces (ASCII 32) and convert back to a string:

This approach fails in three cases: when the string is an empty string or when it does not contain any spaces (in which case “match” fails), or when the string consists exclusively of spaces (in which case “trim” fails).
For a general helper function, these error cases should therefore be handled. For example:

Or a little bit shorter

Thank you,

 

I was trying another approach, was working a long hand that I was going to put in program form. (see attach).  Your approach is much more superior.
