Overflow is only an issue on numeric operations.

Subject: Truncating when concatenating text
All,
Maybe everyone else already knows this. I have a situation where I'm stringing various pieces of text into a single text field. On rare occasions, the length of the text I want to string in _could_ be longer than the text field where I'm storing it. If that happens, I don't want the last piece of text to cause an exception or halt or whatever.
I decided maybe a Monitor group for the last concatenate would be the best so I did a little quickie program to test what would happen. In this program I defined a text field 60A and put in these 2 statements:
Text = 'L18.9000A18.90M19.0700LS22.97AS22.97';
Text = %Trim(Text) + 'L18.9000A18.90M19.0700LS22.97AS22.97';
The 2nd statement will overflow the field. When I ran the test without a Monitor group, I got no error! The program dump shows this:
TEXT CHAR(60) 'L18.9000A18.90M19.0700LS22.97AS22.97L18.9000A18.90M19.0700LS'
so it filled the field and then stopped. That is not what I expected.
I'm going to RTFM to confirm this is expected, but it just startled me.
