Silent startup.

DESCRIPTION:

Tell whether S-PLUS was started in silent mode.

USAGE:

silent.startup() 

VALUE:

a logical value, TRUE if the environment variable S_SILENT_STARTUP had a nonzero value when S-PLUS was started.

DETAILS:

If the environment variable S_SILENT_STARTUP is set to any value except the string "0" (zero) when S-PLUS starts, the system will not print the location of the working database, the copyright messages, or the version information. These are printed by default. silent.startup can be used at any time during the session to determine whether the startup was silent. Applications may wish to use this information in controlling the level of their own messages.

NOTE:

S_SILENT_STARTUP is independent of whether S-PLUS is running interactively or in BATCH mode, and of whether the echo option is set to TRUE.

This mechanism is experimental and may change in future releases.
