... Examples      
 NAME
 
    Set-PSDebug 

 SYNOPSIS
 
    Turns script debugging features on and off, sets the trace level, and toggles strict mode. 

 SYNTAX
 
    Set-PSDebug [-Off] [<CommonParameters>] 

    Set-PSDebug [-Step] [-Strict] [-Trace <int>] [<CommonParameters>] 

 DESCRIPTION
 
    The Set-PSDebug cmdlet turns script debugging features on and off, sets the trace level, and toggles strict mode. 

    When the Trace parameter is set to 1, each line of script is traced as it is executed. When the parameter is set to 2, variable assignments, function calls, and script calls are also traced. If the Step parameter is specified, you are prompted before each line of the script is executed. 

 PARAMETERS
 
    -Off [<SwitchParameter>] 
        Turns off all script debugging features. 

        Note: A "set-strictmode -off" command disables the verification set by a "set-psdebug -strict" command. For more information, see Set-StrictMode. 

        Required?                    false 
        Position?                    named 
        Default value 
        Accept pipeline input?       false 
        Accept wildcard characters?  false 

    -Step [<SwitchParameter>] 
        Turns on script stepping. Before each line is run, the user is prompted to stop, continue, or enter a new interpreter level to inspect the state of the script. 

        Note: Specifying the Step parameter automatically sets a Trace level of 1. 

        Required?                    false 
        Position?                    named

        Accept wildcard characters?  false 

    -Strict [<SwitchParameter>] 
        Specifies that the interpreter should throw an exception if a variable is referenced before a value is assigned to the variable. 

        Note: A "set-strictmode -off" command disables the verification set by a "set-psdebug -strict" command. For more information, see Set-StrictMode.

    -Trace <int> 
        Specifies the trace level: 
         0 - Turn script tracing off 
         1 - Trace script lines as they are executed 
         2 - Trace script lines, variable assignments, function calls, and scripts.
