Effect on $DEVICE

Draft MDC Standard

1.3 Control-functions with an effect on $Device

All controlmnemonics will have a side-effect on special variable $Device. The most common situation will be that $Device will receive the value:

"0,,X3–64"

in order to reflect the correct processing of a controlmnemonic.

In certain situations a status has to be indicated. Status codes for $Device relating to X3.64 are as follows:

codeAmerican English Description

4 hardware error
5 mnemonic not available for this device
6 parameter not available for this device
