Product libraries in the library list

Hi all,

According to the documentation of QUSRJOBI and QLICHGLL there can be two product libraries and one current library in the library list.

The current library can be changed by
- using command CHGLIBL or
- using command CHGCURLIB or
- using API QLICHGLL or
- using a command that has CURLIB specified.

But the only ways I have found to change the product libraries are
- using API QLICHGLL or
- using a command that has PRDLIB specified.

The funny thing is that by using QLICHGLL you can specify two product libraries, but when defining or changing a command you can only specify THE product library. I found out that THE product library is actually product library 1. If I use QLICHGLL to set two product libraries and after that I use a command with PRDLIB(*NONE) only product library 1 is removed; product library 2 remains set. If after that I use another command with PRDLIB(*NONE) product library remains set.

Does anybody know why there are two product libraries in the library list and why a command can only affect the first?
