GetCommandLineParameter Function

Overview

The GetCommandLineParameter function attempts to retrieve a command line argument using the built-in application command line parse object.

Syntax/Parameters

Syntax

string = GetCommandLineParameter ( string name, [int index] );

Parameters

name

A string containing the name of the argument. Parameter names are not case-sensitive.

index

An optional zero-based int specifying the sub item for a series of parameters. This only applies to the Open and InFile arguments.

Return Value

Returns a string containing the data associated with the parameter or an empty string on failure or if the parameter has no data associated with it. Because an empty string does not necessarily indicate an error, use the GetLastError function to determine if an error occurred.

Remarks

When running as an application, there are certain predefined arguments that can be accessed but may either have been processed or only allow certain data to be associated with the argument. All items are listed to indicate reserved keywords so that programmers do not use these values. These are as follows:

	Name		Comment
	client		Reserved. Used for browser plug-in parameters.
	commandfile		Reserved. Used to pass large lists command line arguments to the application. The default max command line size is approximately 4,000 bytes. Using this parameter effecting extends the command line to 65,535 by placing data in an extension file. From the application and script standpoint, all parameters are accessed in the same manner without regard to the source. This parameter is not directly passed to the script.
	decode		Reserved.
	demo		Used to set certain demo modes. Always returns ‘demo’ if present.
	infile		Used to specify one or more input files. This is not processed by the GUI portion of the application but is used by certain API verbs. This is an index-referenced item.
	newinstance		Used to force the creation of a new application instance. Always returns ‘newinstance’ if present.
	nogui		Stops the GUI from opening. Always returns ‘NoGUI’ if present.
	noframe		Reserved. Always returns ‘noframe’ if present.
	nologo		Reserved. Always returns ‘nologo’ if present.
	nomenu		Reserved. Always returns ‘nomenu’ if present.
	openfile		Used to specify one or more files to open. This is an index-referenced item.
	openinfofile		Indicates that the caller asked for an Information View log file to be opened.
	openprojectfile		Indicates that the caller asked for a project file to be opened. A plain file open as a project type will also open a project.
	openmenu		Causes all ribbon and menu items to be available (not grayed).
	outfile		Specifies an output file for an API verb or script.
	parameterfile		Specifies a specific parameter file for an API verb or script.
	parameters		Specifies generic parameters for an API verb or script.
	preferences		Specifies a specific parameter file to be used for the application settings.
	progress		Reserved. Always returns ‘progress’ if present.
	project		Same as ‘openprojectfile’.
	result		Specifies a result file for an API verb or script. All progress and messages are automatically routed to the results file.
	runscript		Forces a script to be run.
	scriptparams		Reserved as a keyword protected for script parameters. The application does not process this item.

 

Within Legato Basic, the above items are not predefined. In addition to the above, the API also has keywords that may be processed.

Note that if the script run is within the GUI and the running instance has received control from another instance, the command line parameters replace the existing instance parameters. Therefore, command line parameters should not be considered static or safe.

To retrieve the raw command line for specific or custom processing, use the GetCommandLine function.
