Example 4

Operation: Enter a fully-qualified data set name as a keyword value in an EXEC command value list.

Known:

The CLIST named SWITCH is contained in a CLIST library named MASTER.CLIST which is allocated as SYSPROC.

The CLIST consists of:

PROC 0 DSN1() DSN2()
RENAME &DSN1 TEMPSAVE
RENAME &DSN2 &DSN1
RENAME TEMPSAVE &DSN2

If you have a user ID of USER33 and you want to switch the names of two data sets MASTER.BACKUP and USER33.GOODCOPY, you can invoke the CLIST as follows:

Explicit form:

exec 'master.clist(switch)' +  
  'dsn1(''''''master.backup'''''') +  
  dsn2(goodcopy)'

Extended implicit form:

%switch dsn1('''master.backup''') dsn2(goodcopy)

Note that when you use the implicit form, the specification of quoted strings in the value list is made simpler because the value list itself is not a quoted string.
