Syntax:	IFNUMxx	[ num1 ] [ num2 ] GOTO [ label ]
Forms:	IFNUM=	[ num1 ] [ num2 ] GOTO [ label ]
	IFNUM<	[ num1 ] [ num2 ] GOTO [ label ]
	IFNUM>	[ num1 ] [ num2 ] GOTO [ label ]
	IFNUM<=	[ num1 ] [ num2 ] GOTO [ label ]
	IFNUM>=	[ num1 ] [ num2 ] GOTO [ label ]
	IFNUM!=	[ num1 ] [ num2 ] GOTO [ label ]
Arguments:	[ num1 ]	Variable, string, or numeric constant defining the first numeric value to compare against.
	[ num2 ]	Variable, string, or numeric constant defining the second numeric value to compare against.
	[ label ]	A valid label within the current script file which is branched to if the numeric condition is satisfied.
Options:	none

This command is used to compare two variables, strings that contain numeric values (e.g., contain only digits 0 - 9), or numeric constants. The command results in a syntax error if either value is non-numeric.

For example, the following conditional branch is taken if the numeric variable x is equal to 1000.

SETNUM x = 1000

IFNUM= x 1000 GOTO EqualValue

The following conditional branch is taken if the numeric variable x is larger than 1000. (Numeric strings are used instead of numeric constants simply as an example of allowed syntax.)

SETNUM x = "2300"

IFNUM> x "1000" GOTO LargerValue

Syntactically, no space is permitted to the left of the ‘!’, '=', '<' or '>' symbols, and a space is required to the right of these symbols.
