This is an OPTIONAL call for passing in Trailer lines so that they appear at the bottom of the last page of the output. The *FIRST call PARM3 controls the positioning of your Trailer output. You may have multiple consecutive *TRL calls if you have more than 5 lines of trailer text. Using *NONE in PARM1 - PARM5 will assume you want a blank line.

Note: If you decide to specify a "Start print line" for your Trailer lines, in your *FIRST call, then you will need to make sure that your detail lines do not output past the chosen Trailer position.

Trailer lines will be replaced on change of Header Key if using an *KEY call.
