Question about dynamic HTML Creation:

I have a parameter in my report that toggles the bold style in HTML here is how I default the &variable:
-SET &IPBOLD = IF '&SORTCOLUMN.EVAL' EQ 'RO_PAIRING_CD' THEN ' style="font-weight: bold; ' ELSE '';

If I am not on RO_PAIRING_CD, I want &IPBOLD to equla '' (the empty string).

When I build my HTML I get a space in the file where &IPBOLD is... I don't understand why.

I am using single pipe concatenation when building the HTML, so I basically have a string | &IPBOLD | another string.

Why doesn't '' give me an empty string?

Am getting same thing on PC Focus 6.40c.
I suspect a dialogue manager variable is designed to take up at least one space when it's defined.

You could get round this by rechecking the &SORTCOLUMN.EVAL when you concatenate (assuming &SORTCOLUMN.EVAL hasnt changed it's value, e.g.


-SET &IPBOLD = IF '&SORTCOLUMN.EVAL' EQ 'RO_PAIRING_CD' THEN ' style="font-weight: bold; ' ELSE '';


-SET &CONCAT1 = IF '&SORTCOLUMN.EVAL' EQ 'RO_PAIRING_CD' THEN
- &STRING1 | ' style="font-weight: bold; ' | &STRING2 ELSE
&STRING1 | &STRING2;
