Using Literal Operands

If you use custom statements to look for a literal value, be sure to put quotation marks (single or double) around the value. The same rule applies to making literal assignments.

If you do not use quotation marks, the system treats a value beginning with a number as a number and a value beginning with a character as an alias.

Note:

The system prevents you from creating alias names that begin with numbers so that the custom statement can make this assumption.
