Simple Expressions in Data Fields

An advanced function of the A command allows addition and subtraction to be performed on constant and variable values in flash printers.

Syntax Ap1,p2,p3,p4,p5,p6,p7,”DATA”[p8p9p10…]

Parameters This table identifies the parameters for this format:

Parameters	Details
p1 through p7, ”DATA”	See the first page of the A command on page 43.
p8 = Required variable	Must be a variable data field number, such as V00, V01, and
data field number	so forth.
p9 = Required operator	Accepted Values: + or –
p10 = 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.
