This program works fine to alternately flash 2 LED's connected to ports 0 and 15:

Start:
Low 15
High 0
Pause 100
Low 0
High 15
Pause 400
Goto Start

If only the first Low/High pair is replaced with OUTS = $7FFF, it still works.

If only the second Low/High pair is replaced with OUTS = $FFFE, it still works.

But if both pairs are replaced together, it fails.

how does it "fail"? also, which version of the IDE and which version of the PRO are you using?

It fails in that neither LED lights.
PRO X (3 days old). IDE 07.1.0.2.

If you replace both low/high pairs the pins are never set as outputs. You must either set the direction of the pins to outputs using the DIRS variable or use the output command.
