SPAWN

The following keywords to the SPAWN procedure are obsolete.

Keywords

FORCE

Set this keyword to override buffered file output in IDL and force the file to be closed no matter what errors occur in the process. If it is not possible to properly flush this data when a file close is requested, an error is normally issued and the file remains open. An example of this might be that your disk does not have room to write the remaining data. This default behavior prevents data from being lost, but the FORCE keyword overrides this behavior.

Macintosh-Only Keywords

MACCREATOR

Use this keyword to specify a four-character scalar string containing the Macintosh file creator code of the application to be used to open the specified files. In no files were specified, the application is launched without any files.

VMS-Only Keywords

NOCLISYM

If this keyword is set, the spawned subprocess does not inherit command language interpreter symbols from its parent process. You can specify this keyword to prevent commands redefined by symbol assignments from affecting the spawned commands, or to speed process startup.

NOLOGNAM

If this keyword is set, the spawned subprocess does not inherit process logical names from its parent process. You can specify this keyword to prevent commands redefined by logical name assignments from affecting the spawned commands, or to speed process startup.

NOTIFY

If this keyword is set, a message is broadcast to SYS$OUTPUT when the child process completes or aborts. NOTIFY has no effect unless NOWAIT is set.
