Jeff, I can't say that I remember seeing this myself. But it seems to make sense. When you say Eval PrintInfo = *BLANKS Just what do you what PrintInfo to have in it? How many blanks: 0,1,2,5,10, 100...? I'd guess it is getting the MAX length number of blanks. Instead what you want is to set the field empty. Try the following: Eval %len(PrintInfo) = 0 HTH, Charles > -----Original Message----- > From: Jeff Crosby [mailto:jlcrosby@xxxxxxxxxxxxxxxx] > Sent: Monday, February 09, 2004 10:49 AM > To: 'RPG programming on the AS400 / iSeries' > Subject: Varying length field issue > > > I've got a program where I build part of the print line in a > field called > PrintInfo.
