Syntax

ISATTY()


See Also

GETENV(), ISMIRAGE(), ISSERVER(), SET UICONTROLS, Terminal Definition Files, UI Commands


Description

The ISATTY() function returns .T. (true) if the current application code is being run on a terminal. If the application is being run as a batch job, ISATTY() will return .F. (false). This allows developers to customize code for the particular environment yet share the same code across all environments.


Example

if isatty()
    // user interface commands can be included
else
    // batch job - no user interface
endif
