Re: Anyone know how to use updHtmlVar2?

[Mel Rothman <mel@xxxxxxxxxxxxxx>]

As Brad pointed out, the length parameter in your code might have been set to 0.

Anyway, here is the quick code sample you asked for, using your data.  Because 
all of UpdHtmlVar2's parameters are passed by value, you can pass literals and 
expressions as well as varibles and you don't need to define the work field, a 
pointer to it, or the data's length.  Therefore, I've removed all the D specs 
leaving only one calculation statement:

 updHtmlVar2('need': %addr(WREQNEED): %len(%trimr(WREQNEED));
