1.2 Variable definition (DEF user-defined variables LUD, GUD, PUD)
This creates a variable of type BOOL with the
name IF_TOO_MUCH.
System initializes with zero (FALSE).
This creates a variable of type BOOL with the
name IF_TOO_MUCH.
A code value for the corresponding ASCII
character or the ASCII character itself
can be assigned to a variable of type CHAR (code
value 65 corresponds to letter "A").
Variables of type string can contain a string
(sequence of characters). The maximum number
of characters is enclosed in square brackets after
the variable type.
The variables of type AXIS have the name
AXIS_NAME and contain the axis designation of a
channel - here X1.
(Axis names with extended address are specified
within parentheses.)
Variables of type FRAME have names like
BEVEL_1.
