The following expressions describe the valid arithmetic operators and calculations available in Global Change.
Addition:Integer + Integer = Integer
Date + Integer = Date
Adding an integer to a date adds a number of workperiods to the date.
Subtraction:
Date - Date = Integer
Integer - Integer = Integer
Date - Integer = Date
If you subtract two dates, the result is the difference between their workperiod numbers.
Multiplication:
Integer * Integer = Integer
Division:
Integer teger = Decimal number to two-digit accuracy
Concatenation:
Use the ampersand (&) as an operator to join text in the first Parameter/Value column with text in the second Parameter/Value column. For example, the following statement results in Activity ID ABCD1234.
Then : Activity ID = ABCD & 1234
