Counters can now contain non-numeric strings as well as proper numbers. Perhaps #1 should be called a variable, just as Alain does. The initial value of a counter is nothing, which will be either the null string or zero, depending on to what the counter is coerced in an expression. set #1:="" causes the counter to contain a null string, which converts to 0 for numerics (perhaps it shouldn't). This also applies when assigning a null value from a column range that is not present in the record.

So (a == " 3339") and (a = 3339) both evaluate to 1 In the numeric example, the string (a) is stripped of blanks and converted successfully to a number for numeric compare. There are a number of quirks with string operands. literal 5|spec a: 1-* 1 if a==5 then ... PIPSPX1086E Improper operand for string expression. It fails because numeric constants are rejected with a string operator (mea culpa). However a string function does not reject a numeric constant: a==strip(5) is processed OK with the result 0 because a has a leading blank, but 5 does not.
Re: [CMS-PIPELINES] IF testing characters
I repeat that #1 (or in France £1) is a counter, so no spaces by definition. I guess that space(#1) converts it to a string and so you can compare to identifier "a", what is a string Kris Buelens, --- VM/VSE consultant, Belgium --- --- Op ma 28 nov. 2022 om 10:07 schreef Alain Benvéniste : > Yes John ^ is the good character. > There is something i still don’t understand : > If i code > If £1==a > and a is equal to b3339 > b for blank, the if is not honored > If I use a > If space(£1)==space(a) it works. > It could mean that when i do a set £1:=a the blank is removed… ? > > Resiliency Services on Z Mainframe > alain.benveni...@kyndryl.com > > > Le 27 nov. 2022 à 14:59, John P.
