= Required variable
data field number
Must be a variable data field number, such as V00, V01, and
so forth.
p

= Required
Variable data field number or constant value.
Accepted Values:
Constant = 0 to 2147483647
Variable = 0 to 2147483647
Result = -2147483648 to 2147483647
• The expression must start with a variable field.
• The character field length defined for the first variable in
the expression will be used to format the result. If the
result is of a greater length than the defined character
length, then the result field will contain ‘X’s.
• A syntax error will be generated during form storage if the
constant value is too large.
• If an error occurs during the evaluation of the expression,
the resultant field will be filled with ‘X’s.
