Users need to declare the type of the Operand string being entered. These types consist of Variables, Constants, Database Items, Elements, and Pay Components.

For example, the string “BIWEEKLY” could represent a Processing Frequency, a database item such as a Group Code or even another UserCalc.

Operand Types declare what value the Operand will have, and how to process it within the UserCalc

The Variable Operand Types available are:
* User Variables ([IMVR])
* Processing Frequency ([IPPF])
* Global Variables ([IMUC])
* Lists ([IMLN])
* Parameters System Constants
* System Variables
* Local Variables ([IMUC])
