cd (MathScript RT Module Function)
Owning Class: support
Requires: MathScript RT Module
Syntax
c = cd
c = cd '..'
c = cd(a)
c = cd a
Description
Returns or modifies the working directory.
Inputs
| Name | Description |
|---|---|
| a | Specifies a new working directory. a is a string. |
Outputs
| Name | Description |
|---|---|
| c | If you specify c = cd, c returns the current working directory. If you specify c = cd '..', c changes the working directory to the parent directory of the current working directory. If you specify c = cd(a) or c = cd a, c changes the working directory to a. c is a string. |
Details
Changes you make to the working directory using this function apply only to the current instance of the LabVIEW MathScript Window or the MathScript Node from which you call the function. Changes to the working directory for one MathScript Node do not apply to any other MathScript Nodes. LabVIEW resets the working directory to the default when you close the LabVIEW MathScript Window or when the MathScript Node stops executing. Use the MathScript: Search Paths page of the LabVIEW MathScript Properties dialog box to change the default working directory for the LabVIEW MathScript Window. Use the MathScript page of the Options dialog box to change the default working directory for MathScript Nodes in the main application instance.
If you call this function from a MathScript Node or a user-defined function, a warning glyph appears in the MathScript Node next to the line from which you call the function. The warning glyph indicates that LabVIEW operates with reduced error checking and slower run-time performance for the MathScript Node. To improve the error checking and optimize the performance of the MathScript Node, remove this function from scripts and user-defined functions. Also, do not change the MathScript search path list at run time. Instead, use the MathScript page to configure the default search path list for MathScript Nodes in the main application instance.
This function is not supported in the LabVIEW Run-Time Engine. Do not use this function in a stand-alone application or shared library.
Examples
C = cd
C = cd '..'
C = cd('C:\Program Files\National Instruments')
