ENVITask::ParameterNames

ENVITask::ParameterNames

The ParameterNames function method returns a sorted list of parameter names for a given task.

Example


See the code example for ENVITask::Parameter.

Syntax


Result = ENVITask.ParameterNames([, ERROR=variable])

Arguments


None

Keywords


ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
