MC-Basic:WRITEIDNVALUE

This command writes the Long Type value of a specified element of an IDN to a specified drive. It is used when writing to an IDN that takes numeric values.

<element> is optional. In general, only element 7 is used (default).

This command is also used to operate a procedure command. In this case, the value 3 is written to begin the procedure, and the value 0 is written to cancel the procedure once it has completed.
