Reference: Usage Notes for Expressions

  • Expressions in Maintain Data cannot exceed 40 lines of text or use more than 16 IF statements.
  • Expressions are self-terminating. You do not use a semicolon to indicate the end of an expression. Semicolons are used only to terminate commands.

Expressions and Variable Formats

When you use an expression to assign a value to a variable, make sure that you give the variable a format that is consistent with the value returned by the expression. For example, if you use a character expression to concatenate a first name and last name and assign it to the variable FullName, make sure you define the variable as character (that is, as alphanumeric or text).
