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
PRINT Instruction
The PRINT instruction controls the amount of detail printed in the listing of
programs.
