If - Else

If is used for branching statements in RVL.

A basic branch statement has two parts: the first row is the If flow with a Condition:

If

Flow	Type	...	Action	ParamName	...
If	Param			param1
	Condition		condition statement
	Param			param2
	some	actions	go	here
End

The actions after the If condition and before the End statement are executed when the condition is true.

If-Else

The If-Else statement is similar to If, with one extension. It contains an alternative Else section that is executed when the If condition is false:

Flow	Type	...	Action	ParamName	...
If	Param			param1
	Condition		condition statement
	Param			param2
#	some	actions	go	here
Else
#	other	actions	go	here
End

If-ElseIf

ElseIf is a way to establish a chain of conditions. Each condition is evaluated only when the previous one is false.

The If-Else statement is similar to If, with one extension. It contains an alternative Else section that is executed when the If condition is false:

Flow	Type	...	Action	ParamName	...
If	Param			param1
	Condition		condition statement
	Param			param2
#	some	actions	go	here
ElseIf	Param			param1
	Condition		condition statement
	Param			param2
#	other	actions	go	here
End

There may be many ElseIf blocks:

Flow	Type	Object	Action	ParamName	ParamType	ParamValue
If	Param			param1
	Condition		condition statement
	Param			param2
#	some	actions	go	here
ElseIf	Param			param1
	Condition		condition statement
	Param			param2
#	other	actions	go	here
ElseIf	Param			param1
	Condition		condition statement
	Param			param2
#	other	actions	go	here
End

An Else block can also be included at the end:

Flow	Type	Object	Action	ParamName	ParamType	ParamValue
If	Param			param1
	Condition		condition statement
	Param			param2
#	some	actions	go	here
ElseIf	Param			param1
	Condition		condition statement
	Param			param2
#	other	actions	go	here
ElseIf	Param			param1
	Condition		condition statement
	Param			param2
#	other	actions	go	here
Else
#	other	actions	go	here
End

Examples

Check if the Log In link is available. If so, log in:

Flow	Type	Object	Action	ParamName	ParamType	ParamValue
If	Action	Global	DoWaitFor	objectId	objectId	Log_In
	Condition		output1 IsSet
#	If actions
	Action	Log_In	DoClick
	Action	Username	DoSetText	txt	string	librarian
	Action	Password	DoSetText	txt	string	librarian
	Action	ctl00$MainContent$LoginUser$LoginButton	DoClick
End

Check if an old version of the OS is in use and assign the OldWindows variable accordingly:
