Task TRN1 prepares data in the FROM(area) which will be written to the QUEUE(name). The passing of data is optional.
TRN2 will start after an INTERVAL of 150000 (hhmmss) has elapsed. The time interval can be zero if the task is required to start immediately.
TRN2 when started will be attached to the terminal PRT5. Again this is optional, there are times when it is desirable to run a task that does not tie up a terminal, for example, long file browses.
TRN2 RETRIEVEs the data that has been passed to it via TS and uses it to SEND data to the terminal PRT5.
