sortinfo question

[Don Coleman]

I am attempting to use the sortinfo command for the first time.  The
following implementation: 

SA=sortinfo(QS1,DELIVERYSHEET,1) 

gives me a syntax error on the comma after QS1.  My filename is QS1, the
output format name is DELIVERYSHEET, and then the actual sort level I am
testing for.

Can someone tell me what the error is and what needs to be surrounded by
quotes?
