The Question is:
1) How can I read from a mailbox created by fortran program using DCL Commands?
2) How can I pause a DCL script to send commands (from the prompt) to a fortran
subprocess without stopping the script?
The Answer is :
Please see the following DCL commands in the DCL HELP library:
$ HELP READ
$ HELP WRITE
Freeware packages which allow better control over mailbox devices
than that available within stock DCL are readily available, as well.
DCL will work for synchronous ASCII text and record I/O operations,
but tends to be very difficult to use for binary records and I/O.
For an example of DCL I/O using READ and WRITE, please see topics
(159) and (7465). Also please see (7359), (1937), (5045) and (5199).
