The STACK
statement is used to place any of the following
into the Natural stack:
the name of a Natural program or Natural system command to be executed;
data to be used during the execution of an INPUT
statement.
For further information on the stack, see Further Programming Aspects, Stack (in the Programming Guide).
Operand Definition Table:
Operand | Possible Structure | Possible Formats | Referencing Permitted | Dynamic Definition | ||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
operand1 | C | S | A | G | N | A | yes | yes | ||||||||||||

Syntax Element Description:
TOP |
If you specify Example: The following statement causes the content of the
variable STACK TOP #FIELDA |
---|---|
DATA |
Delimiter characters or input assign characters contained within
the data values will be processed as delimiters. For details on how data from
the stack are processed by an Example: The following statements cause the contents of the
variables MOVE 'ABC' TO #FIELD1 MOVE 'XYZ' TO #FIELD2 STACK #FIELD1 #FIELD2 These variables will be passed as data to the next
INPUT #FIELD1 #FIELD2 Note: |
FORMATTED |
Examples: The following statements cause MOVE 'ABC,DEF' TO #FIELD1 MOVE 'XYZ' TO #FIELD2 STACK TOP DATA FORMATTED #FIELD1 #FIELD2 ... INPUT #FIELD1 #FIELD2 Assuming the input delimiter character to be the comma
(profile/session parameter MOVE 'ABC,DEF' TO #FIELD1 STACK TOP DATA #FIELD1 ... INPUT #FIELD1 #FIELD2 Note: |
COMMAND operand1 |
To place a command (or program name) in the stack, you specify the
keyword Example: The following statement causes the command
STACK TOP COMMAND 'RUN' |
COMMAND operand1 operand2 ... |
Together with a command (operand1), you
may also place data (operand2) in the stack. These
data will then be processed by the next Data stacked with a command are always stacked unformatted. Note: |
parameter |
If operand2 is a date variable, you can
specify the session parameter |
