Parameters
identifier = identifier specifies the variable name and value you select
for the LET command. The first identifier specifies the variable and
the second identifier specifies the variable value n.
the second identifier specifies the variable value n.
Default
None.
Examples
Long form:
LET X1 = 5.5, X2 = 4.0, Y1 = 3.0;
There is no short form.
Relative coordinate
You can specify all coordinates as literal values or variables. You must
first define variables in the LET statement. Refer to the “LET command”
section for additional information. If you use variables outside of the
LET command, they are called relative coordinates. These coordinates
can also have a positive or a negative value. This allows you to place
text items relative to one another. If you want to shift the whole block of
text up or have to change the initial values. You can shift text
automatically when you add or delete text items.

XFG uses spaces to delimit keywords. Therefore, relative
coordinates must not contain spaces between the variable name Y1
and the value +.5.
I.E. AT Y1+.5 will work while AT Y1 +.5 will not.

identifier is the variable name you specify for the relative
coordinate.
+ or – specifies a positive or negative value that you can apply to the
n value.

Default
None.
Examples
The following examples show the long form of the relative
coordinate variables.
In this example, you can define the Y coordinate as the value of
Y1 plus 3 centimeters:
