Padded with nulls

[LBurkett99]

The %trim(string) built-in usually gives me what I want. But sometimes 'string' is padded with nulls. How can I know when the use %trim(string:x'00')?

Simple answer is you can't unless you have some other "flag" that will tell you which to use.

But there's no reason you can't use both. You said %Trim but I assume since you were talking about padding that you meant %TrimR. This code appears to do what you want.

dcl-s string char(20) inz('ABCDEFGHI');
dcl-s newString varchar(20) inz;
dcl-c trimChars x'0040';
%subst(string: 16) = *allX'00';  // set last 5 chars to null following blanks
newString = %TrimR(string: trimChars);
Dsply ( newString + ' is ' + %Char(%Len(newString)) + ' long');
