My best guess is that I've never tried this before:
myVar = *blank;
myVar += 'abc';


Thanks

The 'cardboard analyst' strikes again :-) http://imho.midrange.com/2005/12/18/cardboard-analyst/

I'm concatenating the column values together into a single varchar() variable. After each row is processed, I set the varchar() variable to blank (myVar = *blank;). Apparently that also pads myVar with blanks so the next time I try to append a new value (myVar += columnValue;) nothing happens. I can't believe I've never encountered this before.

I got burnt by this long ago, when varying was first introduced. Harsh lesson, but still never forgotten :-/

For those following along in the archives:

dcl-s thisVar varchar(25);
// load 25 blanks into thisVar
thisVar = *blanks;
// clear thisVar
thisVar = '';
