This Natural profile parameter is used to place data/commands on the Natural stack.
Note:
If STACK is used, a colon (:) must be
specified with the profile (or session) parameters DC, HI, IA and
ID .
| Possible settings | any character string |
|---|---|
| Default setting | none |
| Dynamic specification | yes |
| Specification within session | no |
The profile parameter STACK is used to place
data/commands on the Natural command stack. The amount of data to be passed
with this parameter is limited to 512 bytes. If this limit is exceeded, a
corresponding error message is returned.
The stack can contain a sequence of Natural commands and/or user-specified commands, together with their data, for execution at the beginning of the Natural session. The command stack is processed before the user is prompted for input on the screen.
If an INPUT
statement is encountered during stack processing, the corresponding input
screen is generated only if the required input data were not supplied with the
command when the stack was created. Any reports generated during stack
processing are displayed as usual.
Each system or user-defined command can be optionally followed by data
which are used to satisfy requests for information required during the
processing of the command. If the command is a user command (that is the name
of a user program), any data provided resolve the data requirements of
INPUT statements within
the user program.
Multiple settings for one INPUT statement are separated by
a comma. Data for multiple INPUT statements are separated by a
colon (:). A semicolon (;) is used to delimit multiple commands, for
example:
LOGON:USER1;UCMD1 A,B;UCMD2 C,D:E;FIN
Logs on to the library USER1, executes the commands
UCMD1 and UCMD2 providing
the corresponding input data, and ends the Natural session.
CMD DATA:DATA;CMD
Places commands and data on stack. Since some commands (for example,
GLOBALS) do not read parameters by
INPUT, a blank character should be used rather than a colon to
delimit a command from the first parameter data element.
If specified dynamically, the character string provided as data for the
STACK parameter must be enclosed in apostrophes; if the
character string contains multiple commands, it must also be enclosed in
parentheses, for example:
STACK="(LOGON SYSTEM;UCMND)"
Logs on to the library SYSTEM and executes the command
UCMND.
