View source for F$MODE()

'''F$MODE()''' is a [[Lexical functions|lexical function]] that returns a character string showing the mode in which a process is executing. The F$MODE function has no arguments, but must be followed by parentheses.

=Syntax=

F$MODE()

=Return Value=

The character string INTERACTIVE for interactive processes. If the process is noninteractive, the character string BATCH, NETWORK, or OTHER is returned. Note that the return string always contains uppercase letters.

=Examples=

 $ IF F$MODE() .NES. "INTERACTIVE" THEN GOTO NON_INT_DEF
 $ INTDEF:         ! Commands for interactive terminal sessions
          .
          .
          .
 $ EXIT
 $ NON_INT_DEF:         !Commands for noninteractive processes
          .
          .
          .


This example shows the beginning of a login.com file that has two sets of initialization commands: one for interactive mode and one for noninteractive mode (including batch and network
jobs). The IF command compares the character string returned by F$MODE with the character string INTERACTIVE; if they are not equal, control branches to the label NON_INT_DEF. If the
character strings are equal, the statements following the label INTDEF are executed and the procedure exits before the statements at NON_INT_DEF.
