PUSH instruction
The PUSH instruction saves the current PRINT, USING
or ACONTROL
status in push-down storage on a last-in, first-out basis.
You restore this PRINT, USING
or ACONTROL
status later, also on a last-in,
first-out basis, by using a POP instruction.

Notes:
- Each keyword from this group may be selected only once.
- sequence_symbol
- is a sequence symbol.
- PRINT
- instructs the assembler to save the PRINT status in a
push-down stack.
- USING
- instructs the assembler to save the USING status in a
push-down stack.
- ACONTROL
- instructs the assembler to save the ACONTROL
status in a push-down stack.
- NOPRINT
- instructs the assembler to suppress the printing of the PUSH
statement in which it is specified.
The PUSH instruction only causes the status of the current PRINT,
USING
or ACONTROL
instructions to be saved. The PUSH instruction does not:
- Change the status of the current PRINT
or ACONTROL
instructions
- Imply a DROP instruction, or change the status of the current USING
instructions
