If / Else / EndIf

If, Else, and EndIf control execution flow based on a conditional test included with the If script statement. Adding an If command automatically inserts a matching EndIf command. Any number of commands can then be placed between the If and the EndIf.

Once an If command has been added to a script, an Else can optionally be added.

Syntax:	If	Expression	Comparison	Expression	Comment
Syntax:	Else				Comment
Syntax:	EndIf				Comment
A set of comparison operators are supported
Comparison:	If	Expression	contains	Expression	test if first expression text contains 2nd expression text
Comparison:	If	Expression	!contains	Expression	test if first expression text does not contain 2nd expression text
Comparison:	If	Expression	==	Expression	test if comparison is equal
Comparison:	If	Expression	!=	Expression	test if comparison is not equal
Comparison:	If	Expression	>	Expression	test if first expression is greater than 2nd expression
Comparison:	If	Expression	<	Expression	test if first expression is less than 2nd expression
Comparison:	If	Expression	>=	Expression	test if first expression is greater than or equal to 2nd expression
Comparison:	If	Expression	<=	Expression	test if first expression is less than or equal to 2nd expression
Example:	If	metric	==	0	test if metric = 0
	instructions added between the If and EndIf are executed only if the If condition is true
	EndIf
By right clicking on an If, an Else may be added between the If and the EndIf
Example:	If	metric	==	0	test if metric = 0
	instructions added between the If and Else are executed only if the If condition is true
	Else
	instructions added between the Else and EndIf are executed only if the If condition is false
	EndIf

Notes:

• All instructions between the If, Else, and EndIf are indented automatically
• If, Else, EndIf instructions can be nested with progressive indenting managed automatically
• Deleting instructions is limited such that If, Else, EndIf instructions are not inadvertently unbalanced. Else instructions can be independently deleted, but If and EndIf instructions must be deleted together such that balance is maintained
• "Contains" and "!Contains" always compare both expressions as text
• For all comparisons other than "Contains" and "!Contains"
  • If both expessions evaluate to numeric results, comparison is of resulting numeric values
  • If either expession does not evaluate to a numeric result, comparison is of resulting text alphabetical values
