Prototype

	function get_script_prefix_name (
	)
	return_val [1] : string

Returns a singly dimensioned string containing the name of the file of commands, if provided, to NCL for execution, with the script name tag removed.

This function returns the name of a script of commands that NCL was invoked with, if provided, with the script name tag removed.

Example 1

Print the name of the command file provided to NCL. If NCL is invoked as:

% ncl myScript.ncl

the script itself can announce how NCL was invoked:

 script_name = get_script_prefix_name() ; string
 print(script_name) ; Or, just print(get_script_prefix_name())

The following string is returned:

myScript

Example 2

If no script is provided to NCL, the default missing value for type string is returned. If NCL is invoked as:

% ncl

the function will return:

 print(get_script_prefix_name())
