Restrictions
Do not:
- Specify both dependent and independent variables as setup variables, if the independent variable is part of a compound variable that cannot be resolved at the setup phase.
- Specify a setup or promptable dependent variable if the independent variable is resolved at submit.
- Cause a loop by making a variable directly or indirectly dependent on itself.
- Give a dependent variable a blank value, if
VALUE REQUIRED=Yis specified for that variable. - Use a variable substitution exit to set the value of the independent variable.
The dependent variable is given its value on the first pass of
variable substitution, and you should be careful if the independent
variable needs several passes to resolve. For example, if you gave
SYSTEM a value &OWSID. (which is substituted further, because
it is a scheduler-defined variable), MSGC will not be substituted
correctly, unless you specify the literal &OWSID. as
the value for the independent variable, which is probably not what
you want. If you need to make MSGC dependent on the workstation name,
the correct method is to make OWSID the independent variable. See Using supplied variables for a description of this method.
