The STP function can now accept string strip types operators.
The problem can be seen on a line entered as:
The system syntax checks accepts the line however during execution it failed with an error 26.
At issue is that the STP function accepts a string strip type ("L", "R", "C", "A", or "B") and as such the syntax of a STP function can be
STP (String$, String$)
However you will get a run-time error if the second string is not one of the possible stripping forms.
This can prove difficult to detect and debug due to the fact that forgetting to include a strip type value would be a common typing mistake.
