!!$G - Global Variable

Global Variables are variables that hold their value beyond the existing UserCalc; the value will not be lost once the UserCalc has completed. In this way they differ from local variables, which hold their value only for the current UserCalc.

The value of a global variable may be calculated in one UserCalc, and then referenced, edited or used by another UserCalc. For this reason, timing is important when accessing and modifying global variables. 

A global variable must exist prior to creating the line within a UserCalc that refers to it. 

;Statement:If the employee is in the Full-Time unit return TRUE, otherwise return FALSE.

||Line||CMD||OT||Operand 1||OPER||OT||Operand2||OT||Operand3||If Goto||	Else GoTo
|00010|	IF|	DB|	DUN.UNIT|	EQ|	A|	FULL-TIME|  |  |00100|	00200
|00100	|LET|	$G|	FULL-TIME|	EQ|	B|	TRUE|	  |  |99999|	
|00200|	LET|	$G|	FULL-TIME|	EQ|	B|	FALSE|	|  |99999|	
|99999|	RET|	$G|	FULL-TIME|	|	|		|  |  |99999|	

;Statement:If the employee is in the Full-Time unit (as determined in the previous UserCalc and stored in global variable FULL-TIME) then calculate the Union Dues, otherwise exit.

In this example, we can see that Operand 1 (Full-Time) in Line 00100 of the previous UserCalc is now used in Line 00010 of the UserCalc below. 

If the employee is full time, Line 00100 tells the UserCalc to calculate 1.5% (Operand3) of their gross pay (Operand2).   Line 00110 then instructs the UserCalc to round that amount to the nearest cent (Operand3).

||Line||CMD||OT||Operand 1||OPER||OT||Operand2||OT||Operand3||If Goto||	Else GoTo
|00010|	IF|	$G|	FULL-TIME|	EQ|	B|	TRUE|  |  |00100|	99999
|00100|	LET|	PC|	300|	PERC|	EC|	GROSS PAY|	N|	1.5|	00110|	
|00110|	LET|	PC|	300|	RDN|	PC|	300|	N|	.01|	99999|	
|99999|	EXIT|  |  |  |  |  |  |  |99999	|

Global variables may be created, viewed, modified or deleted in the Globals tab of the [Define UserCalcs (IMUC)|IMUC] form. 
UserCalc Global Variables data is stored in the [P2K_AM_USER_CALC_GLOBALS] table.
