GOTO_LINE is a field which must be completed for every line in a user calc.
For any IF, FREQ, PPE, BOM, or EOM command there must be a true path (If Goto), and a false path (Else Goto).
The If Goto field tells the UserCalc program which line to proceed to in a True situation. In a situation without a true and false path (i.e. Let PC 110 Equal +12), only the If Goto field is mandatory.
If the If Goto column is double-clicked on the user will be taken to that line.
