In the past, I've utilized SK's, aka The Great One, nifty little utility
employing regular expressions within RPG. It's worked great for me up until
now. So I figure I'm overlooking something.
I have a 20-character field (bank account) that needs to only contain blanks
or digits. In addition, the digits must be contiguous and right aligned.
Some examples are:
'12345678901234567890' (good)
' 67890' (good)
' #67890' (not good)
' 56789 ' (not good)
This is what I'm using for the pattern: '^[ ]*[0-9]+$'. I've also tried
coding it this way: '^\s*\d+$'. It works, mostly, but doesn't flag the last
example as a bad string. I would have thought the end-of-string anchor would
flag the string as bad, unless it stops checking after the digit '9' thereby
ignoring the space in the last position of the string.
