Eval String Function

I would like to trim down a field to 5 characters using an Excel Left Logic. I have read some suggestions to use LEN, but the length of the field is not fixed.

In Python I would do something like this:

newvariable = 'blahblahblah'
newvariable[0:4]
blahb

I believe what you are looking for is "substr"
