| Description |
The FindCmdLineSwitch function scans the command line (program + parms used to invoke the current program) for a given parameter switch. It saves the coder from this parsing activity.
Switches are optional parameters prefixed by :
- / for Windows
- for Linux
but may be specified in SwitchChars in Version 3 of the function.
The SwitchValue follows this prefix character, and is the value scanned for in the command line by this function.
The IgnoreCase parameter in Versions 2, 3 of the function determines whether the scan ignores the case of the SwitchValue. The default is True |
