PUN(nn) - Local Card Punch

The PUN(nn) statement specifies the characteristics of one local card punch. Each punch device is defined by a PUN(nn) statement with a unique value (1-99) specified for nn. Punch characteristics are specified by the following parameters.

The dual reader/punch feature is supported by JES2 as shown in the following example. Assume that a 3525 with the read feature has a unit address of 013 and that the following two items appear in the JES2 initialization data set:

RDR(2)  UNIT=013,START=NO
PUN(1)  UNIT=013

When JES2 is started, the reader will be stopped and the punch feature will be activated. If the operator later wants to read data from the 3525, he can stop punch 1 and start reader 2 with JES2 commands.
