How GDIF Reorders the Exempt List at Startup Time

At startup time, GDIF handles the LOCAL and GLOBAL statements by concatenating the QNAME first, and then the RNAME for any statement on which the RNAME parameter is specified. GDIF appends blank characters to QNAMEs that are less than 8 characters long and uses 8 pound (#) characters to represent a QNAME if a QNAME is not specified on that statement. GDIF then reorders the LOCAL and GLOBAL statements according to these rules:

• By the number of significant characters in the QNAME/RNAME string or in the job name. For example, GDIF orders a statement that contains the value ########/SYS1.LINKLIB (with 12 significant characters) before a statement that contains the value SYSDSN##/SYS* (with 9 significant characters).

  Note: Significant characters are non-wildcard characters, including blanks.

• By the number of leading significant characters (for statements that have the same number of significant characters). For example, GDIF orders a statement that contains the value SYSDSN##/SYS* (with six leading significant characters) before a statement that contains the value ########/SYS1.LINK* (with no leading significant characters).

  Note: Use the DISPLAY EXEMPT command to view the current reordered list.
