Program execution
If there is no item target in buffer or any item targets above the Limit, the program
execution waits in this instruction until there is an item in the buffer.
If the MaxTime argument is specified then the wait time is supervised. If the waiting
time exceeds the value of MaxTime and the TimeFlag argument is used, then the
program will continue. If TimeFlag is not used, then an error is raised. If TimeFlag
is specified, this will be set to TRUE if the time is exceeded, otherwise it will be set
to FALSE.
Error handling
The following recoverable errors can be generated. The errors can be handled in
an error handler. The system variable ERRNO will be set to:
Error code
