Personally, I wouldn't want to force the user to type everything right-aligned. Why make the user do this when it's just as easy to have your program adjust it to the right?

Do something like this:

evalr BankAcct = %triml(BankAcct)

As for checking that it consists only of digits, I'd use the %CHECK BIF to keep things simple.

if %check('0123456789': %trim(BankAcct)) > 0;
// bad data in BankAcct
endif;

That's my thought, anyway.

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.
