Description
Selection of a program for processing in a certain
channel:
Acknowledgment mode: n (without) or s (synchronous)
Name of the program with specification of the path
Number of channel: Values 1 to 4 possible
Deletion of a program by indicating the program identifier
Starting the selected programs in other channels.
Enumeration of the channel numbers: Values 1 to 4
possible
Waiting for tag number Mnr for synchronization in the
specified channels n (own channel can be, but must not
be specified).
The tag number must be the same in all channels.
Numbers 0 to 9 are possible.
Waits for the end of program of the specified channels
(current channel not specified)
Set wait marks Mnr1, Mnr2, ...Mnri for conditional wait
with WAITMC() for the channel in which SETM() is
issued. The channel thus declares its wait characteristics
for the partner channels as fulfilled.
The command can be activated in synchronized actions.
Up to 10 marks (0-9) can be set using one command.
Delete wait marks Mnr1, Mnr2, ...Mnri for conditional wait
with WAITMC() for the channel in which CLEARM() is
issued. The channel thus declares to its partner channels
that its wait characteristic is fulfilled.
The command can be activated in synchronized actions.
Up to 10 marks (0 - 9) can be deleted using one
command.
Conditional wait in continuous-path mode for the
specified wait characteristic Mnr from the specified
channels n1, n2, ... nk. The current channel can be
specified, but this is optional. When processing continues
after the wait marks from the other channels in the group
have arrived, the wait marks of these channels are
deleted.
