State

Explanation

Non-selected

No program selected. (MMS = Non-selected)

Unrunable

The program cannot run. (MMS = Unrunable)

Idle

The program is stopped and reset. (MMS = Idle)

Running

The program is running. (MMS = Running)

Stopped

The program is stopped. (MMS = Stopped)

Starting

The program is changing state from idle to running.

(MMS = Starting)

Stopping

The program is changing state from running to stopping.

(MMS = Stopping)

Resuming

The program is changing state from stopped to running.

(MMS = Resuming)

Resetting

The program is changing state from stopped to idle.

(MMS = Resetting)

SelectedProgram holds the library index for the selected program. SelectedProgram is 0, if State

is Non-selected.

ErrorStatus is identical to ProgramControl.ErrorStatus, but only read access is possible. All bits

in ErrorStatus always read FALSE.

SWNo $D2: ProgramID

ProgramID is used to identify the selected program. The record includes a name for the program,

version number, the required version number for the interpreter program and a name of the

software house that created the program. Compile time, compiler version and actual size for the

program is also a part of ProgramID, as well as SumCheck (2's complement word addition without

carry), and a code type identifier. The SumCheck value is used for check sum calculations when

the program is started, i.e. following a Start command (40) or a Resume command (42). CodeType

must match CodeType found in ChType. The CodeType check is performed at the same time as

the SumCheck.

ProgramID is a record of the following structure:

Record

(* Offset = 22 *)
