OPNQRYF QRYSLT CPF9899 Al Mac

My OPNQRYF statement is failing on CPF9899
"Missing Operator in Expression in QRYSLT parameter"

I am hoping that it jumps out to someone knowlegeable with this stuff, where MEKLUTZ has el typo, overlooked something obvious, or something missing from the syntax.

I don't use Open Query File often enough to be skilled at it.
I am on V5R1.

I copied this code from another CL that works, then I changed name of file, names of parameters, fields, tests, etc. to what was wanted, and in the process, probably missed some nuances with syntax. Key fields are transcribed from RARL94 DDS.
