tranperform validation needs some work

TRANPERFORM WF (0, tranSEQ1, tranSEQ2, tranCHECKCODE, tranCHECKNUM, cERROR)  
DO
    SET GLCODE TO 123
    SET FMTYPE TO "S"
    SET FMID TO SID   
    SET AMOUNT TO FEE  
    SET COMMENT:1 TO "Stop Payment Fee"
END

Erroneously reports:

Cannot assign 'NUMBER' value to 'CHARACTER' token 'GLCODE'

and

Invalid transaction token 'COMMENT:1'

neither of these errors are correct.
