Programming Examples
The following examples are related to an IBM-compatible PC. The first one uses the
built-in IEEE-488 Interface, the second one uses the standard serial port of the controller
and the RS-232 Interface. You should have basic knowledge of the MS-DOS operating
system of your controller and the programming language QuickBasic (version 4.0 and
above) to understand the examples that follow.
Example for the IEEE-488 Interface

DECLARE SUB SendStr (WR$)
DECLARE SUB ErrChk (Cs!, Sts%)
