EXECUTE

EXECUTE [REPEAT]   program-name   [library-id]

program-name [parameter ...]

This command is used to execute a Natural object module of type program. The object module must have been cataloged (that is, stored in object form) in the Natural system file or linked to the Natural nucleus. The execution of an object module does not affect the source code currently in the editor work area.

This document covers the following topics:

Syntax Explanation

EXECUTE The keyword EXECUTE is optional; it is sufficient to specify program-name, i.e. the name of the program to be executed.

Caution:
When entered in the command line of the program editor, the system command EXECUTE must not be abbreviated to EX, as the program editor would interpret this as the program editor command EX.

REPEAT If the program being executed produces multiple screen output and you wish the screens to be output one after another without intervening prompts, you specify the keyword REPEAT together with the keyword EXECUTE.
program-name The name of the program to be executed. If you do not specify a library-id, Natural can only execute the specified program if it is stored either in your current library or in the current steplib library (the default steplib is SYSTEM).
library-id

If the program is stored in another library, specify the library-id of that library. In this case, the program can only be executed if it is actually stored in the specified library.

A library-id that begins with SYS must not be specified (except SYSTEM).

parameter

When you execute a program by specifying the program name without the keyword EXECUTE, you may pass parameters to the program. These parameters will be read by the first INPUT statement in the executed program.

You can specify the parameters as positional parameters or as keyword parameters, with the individual specifications separated from one another by blanks or the input delimiter character (as specified with the session parameter ID).

Note:
The parameter values are always converted to upper case (regardless of the terminal command %L or the profile parameter LC=ON).
