[CLOSED] TRUNCATE in a Function?
Hi All,

I've haven't done too much work with Functions. I often just use an include statement for the sake of modularity (but I don't feel that's good practice).

I would like to know why I am having problems with the following function. This function should take a parameter (QUOTE_ME) and add quotes in the right spots if they do not exist (in the case of strings). If quotes do exist then the input should match the output.

DEFINE FUNCTION QUOTEANATOR(QUOTE_ME/A1000)
    QUOTE_ME = TRUNCATE(QUOTE_ME);

    QUOTE_ME = STRREP (QUOTE_ME.LENGTH,QUOTE_ME,1,'''',0,'',1000,'A1000');
    QUOTE_ME = TRUNCATE(QUOTE_ME);

    QUOTE_ME = '''' || STRREP (QUOTE_ME.LENGTH,QUOTE_ME,4,' OR ',6,''' OR ''',1000,'A1000') || '''';
    QUOTE_ME = TRUNCATE(QUOTE_ME);

    QUOTEANATOR/A1000 = QUOTE_ME;
END

The error message I get is:

(FOC263) EXTERNAL FUNCTION OR LOAD MODULE NOT FOUND: TRUNCATE

Anyone know why TRUNCATE doesn't work? Am I making some syntax error? I've tried to put a - at the start of the lines, but that wasn't successful. I am using other Functions that I have created and used for a long time as templates, and they work fine.

Thanks again great community!

How about replacing TRUNCATE with RTRIM ?


Also, I don't like the reuse of fields especially without a format.

Did not know that TRUNCATE exist in WF...

Look at the following functions

@martinY

actually, it does. But only als a DM command.

-SET &A = 'bye bye                     ';
-SET &B = TRUNCATE(&A);

-TYPE &A.LENGTH
-TYPE &B.LENGTH

Um, ok... I'll try RTRIM. But why doesn't TRUNCATE work? Is it because it is a DM command, and DM commands don't work in functions?

Thanks!

Shingles, because it is part of DM Language and not part of the FOCUS language. That is like asking why the COBOL MOVE command doesn't work in JCL.

Thanks jgelona... and I'm guessing DM isn't allowed in Functions. I haven't been at FOCUS for long, so this is news to me.
