Alphanumeric OT	Used to represent constants referred to as Alpha, Char, Character, or String
Boolean OT	Used when only the value True or False may be entered in the Operand.
Calculation	The main routine or procedure usercalc. Calculations may make use of Qualifiers and/or Functions, and are able to modify values of pay components.   Calculations are used exclusively by the Payroll application.  
CMD	Command
Commands	Used to perform operations within a UserCalc.
Comparison Operators	Allows the UserCalc to compare two values
Database Fields	Allow the user to access a large amount of information about the employee from within a UserCalc.
Date OT	A string that should be interpreted as a date by the program.
Disbursement Messages	The lines of information that will print on the employee’s payroll stub/deposit stub.  
Elements	A group of pay components that, for convenience in calculations, are added together and named, and may be referenced by Calculations, and in some instances, Functions and Qualifiers.  
Function	May return a Boolean, Char(acter), Date, or Number value.    Functions may be part of a Calculation UserCalc as a CALL, or may be a stand alone UserCalc for the Attendance or Benefits modules.
Global Values	Used to hold information between UserCalcs for one employee. 
Global Variables	Variables that hold their value beyond the existing UserCalc.  
Lexicon	Provide a controlled set of values, which a particular field may contain.
Lists	Used in order to simplify the number of UserCalc lines it would take to eliminate employees from the selection.
Number OT	Any numeric amount.   
Operand Types	Used to declare what value the Operand will have, and how to process it within the UserCalc.
Operator	Defines the action that is to be applied to the Operands indicated.
OT	Operand Type
Parameters	These are number amounts, character strings, Boolean values, or date values that are passed automatically to Functions and Qualifications UserCalcs.  
Processing Frequencies	Define the timely manner under which a payroll item (deduction, benefit, etc) is processed.   
Qualifier	Returns a Boolean value of either True or False.  It is used to either eliminate or include employees in a calculation.  Qualifiers may be part of a Calculation UserCalc as a CALL.  
Relative Date Operators	Allows the UserCalc to return the value of a date relative to another date.  
Round Nearest	Defines the level of rounding within a UserCalc.
Statistics	Used to hold information for each employee that is not easily accessed with Pay Components. 
System Constants	Provided by High LineMcKesson to allow the user access to typically required dates
System Variables	The amounts calculated by the FLSA process ONLY.
User Variables	A type of variable whose value is defined by the user.  
UserCalc	A set of user-defined instructions that tells the execution program (UPCALC, UFCALC, etc.) to perform an action or operation.  
Variables	Used as temporary working storage to hold values required by the UserCalc.  
Wage Basis	A Wage Basis type is used with the WAGE operator
