This is some long-standing, documented and entirely expected DCL stupidity.

Quoth the f$getqui docs:

"Restriction

The GQC that is saved for wildcarded F$GETQUI calls is destroyed if you 
run any DCL queue-related command, such as SHOW QUEUE or SHOW ENTRY. To 
avoid this problem, use the SPAWN command to create a new process in 
which to run the DCL commands."
