* !EXIST subroutine returns success=1 if subroutine.name exists in catalog
* spcae otherwise it returns success=0. Also refer to newacc which defines
* GLOBAL.CATDIR . Prime information implimentation also returns status function
* code to indicate the number of arguments to subroutine.Since currently there
* is no way of setting status function in a basic program this subroutine call
* does not return number of arguments to the catalog program              -GPS
