The POP instruction restores the PRINT, USING, or ACONTROL status saved by the most recent PUSH instruction.

Notes:

Each keyword from this group can be selected only once.

sequence_symbol: Is a sequence symbol.
PRINT: Instructs the assembler to restore the PRINT status to the status saved by the most recent PUSH instruction.
USING: Instructs the assembler to restore the USING status to the status saved by the most recent PUSH instruction.
ACONTROL: Instructs the assembler to restore the ACONTROL status to the status saved by the most recent PUSH instruction.
NOPRINT: Instructs the assembler to suppress the printing of the POP statement in which it is specified.

The POP instruction causes the status of the current PRINT, USING or ACONTROL instruction to be overridden by the PRINT, USING or ACONTROL status saved by the last PUSH instruction. For example:

          PRINT  GEN                    Printed macro generated code
          DCMAC  X,27                   Call macro to generate DC
+         DC     X'27'                  ... Generated statement
          PUSH   PRINT                  Save PRINT status
          PRINT  NOGEN                  Suppress macro generated code
          DCMAC  X,33                   Call macro to generate DC
          POP    PRINT                  Restore PRINT status
          DCMAC  X,42                   Call macro to generate DC
+         DC     X'42'                  ... Generated statement
