DEFINEs
DEFINEs
A DEFINE is a named set of attribute/value pairs. DEFINEs are similar to ASSIGN
messages, but more versatile. DEFINEs involve too many commands to be described
completely here.
Topics:
•
DEFINE and ASSIGN
•
Controlling the Propagation of DEFINEs
•
DEFINE Names
•
DEFINE Attributes
•
ADD DEFINE Command
For more information on DEFINEs:
DEFINE and ASSIGN
Both DEFINEs and ASSIGN messages allow you to specify information about a file
before you start the process that uses that file.
Example 12-5. CLEAR Command
43>CLEAR ALL { Clears all ASSIGN and PARAM values }
44>CLEAR ALL ASSIGN { Clears all ASSIGN values }
45>CLEAR ALL PARAM { Clears all PARAM values }
46>CLEAR ASSIGN in-file { Clears assignment for in-file only }
47>CLEAR PARAM DEBUG { Clears the DEBUG switch }
