and “DATA” parameters -
See first page of A command, page 3-4.
p
8
= Required. Must be a variable data field
number, e.g. V00, V01 etc.
p
9
= Required. Operator, + or –
p
10
= Required. Variable data field number
or constant value.
Valid Number Ranges:
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 for-
mat 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
store 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.
