Order of Precedence for Multiple Value Assignments

If a particular AutoEdit variable can receive a value from more than one source, an order of precedence is necessary to determine which of the possible values is assigned.

The following chart indicates the order of precedence. The chart works as follows:

• Each row in the chart represents a possible source of a value for a variable.
• In each column, a single pair of value sources (rows) are selected and compared for precedence:
  • The source that takes precedence in the pair is identified by label P.
  • The other source in the pair is identified by label O.

When many sources of value assignments are available for a variable, use the chart below to compare those sources one pair at a time, as follows:

• From the list of available sources for the particular variable, select any two sources and use the chart to eliminate the source of lower priority. The list now has one less source available.
• Repeat this process until only the source of highest priority remains.

  Table 256 Chart for Determining Priorities of Value Assignment Sources

  Source of Value Assignment	Paired Combinations of Value Sources
  SET VAR (Job Scheduling Definition)	O	P	P
  JCL SET (earlier)	P			P	P		O
  JCL SET (later)							P
  LIBSYM		O		O		P		P
  LIBSYM2								O
  GLOBAL			O		O	O			P
  GLOBAL2									O

Note: JCL SET can apply to an actual AutoEdit SET statement in the JCL or to AutoEdit SET statements embedded within an INCLIB member referenced in the JCL. LIBSYM represents a member specified in an earlier statement; LIBSYM2 represents a different member specified in a later statement. The same applies to GLOBAL and GLOBAL2 respectively.

If there are multiple value assignments for the same variable in the one member, the last assignment in that member is used for the above calculation.
