Basically it's the whole DELETE/SYMBOL thing i needed to do to clear out the old copy. Now I know. :) ;) You need to appreciate the whole symbol defintion and scope thing. There are both GLOBAL and LOCAL symbol definitions in DCL. A GLOBAL symbol can be resolved from ANY procedure level. A LOCAL symbol can only be resolved in/at the procedure level in which is is/was defined. $ SET NOON $ XYZZY = "this is a local symbol" $ SHOW SYMBOL XYZZY $ CALL MYSUB $ SHOW SYMBOL XYZZY $ EXIT $ $ MYSUB: SUBROUTINE $ SHOW SYMBOL XYZZY $ XYZZY = "redefine this local symbol" $ SHOW SYMBOL XYZZY $ EXIT $ ENDSUBROUTINE -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG Well I speak to machines with the voice of humanity.
