You execute REFSPEC by entering the following command in response
to the MPE colon prompt:
Since REFSPEC runs entirely in block mode, your terminal is
placed in block mode automatically.
Like FORMSPEC, REFSPEC prompts for information on menu screens.
The information you enter on these menus defines how data in the
batch file is to be reformatted and written to an output file. The
first menu issued whenever you run REFSPEC is the Reformat File
Menu.
If you specify a new reformat file, REFSPEC creates this file
and then issues the Forms File Menu so you can specify the forms
file through which the data to be reformatted was entered. If you
specify an existing reformat file, it is already associated with
a forms file so the Forms File Menu is not issued, and the Main
Menu is the next menu.

|
 | NOTE: If your file has a lockword, you must enter
the lockword along with the file name, as filename/lockword.
If you do not enter a lockword with the file name and one is required,
your terminal hangs. This is because the MPE prompt requesting the
lockword is in character mode and cannot be received while your
terminal is in block mode. You can recover from this error by doing
a hard reset followed by pressing RETURN at least four times, then pressing f8 to exit. How you
perform a hard reset depends on what type of terminal you are using;
consult your terminal manual for instructions. |

Terminating REFSPEC |
|
You can terminate operation of REFSPEC at any time by pressing EXIT to return to MPE control, indicated by the colon
prompt (:).
When you next run REFSPEC after terminating and request the
same reformat file, the Forms File Menu is skipped and the Main
Menu is displayed on the screen. You may then select an option on
the Main Menu or you can press MAIN/RESUME to display the Forms File Menu. If you specify
a new reformat file on the Reformat File Menu, the next menu issued is
the Forms File Menu.
Unexpected Program Interruption |
|
As with FORMSPEC, if the program halts unexpectedly because
of a terminal power failure or the user pressing BREAK, control returns to MPE. Refer to Appendix G for the steps
to recover from such a situation. After you have recovered, you
then press REFRESH to return to the REFSPEC Menu where you were interrupted.
The menu is cleared to initial or previously entered values. To
ensure against damage to the file, reenter the information on all
menus pertaining to the reformat you were creating or modifying
at the time of program interruption.
REFSPEC Function Keys |
|
A set of seven function keys, similar to those used for forms
design, are used to control execution of REFSPEC. These keys are
described in Table 5-1 “Key Definitions”
Table 5-1 Key Definitions
Key | Key Action |
|---|
PREV FORMAT f1 | Go to previous Input Forms Menu (skipping
any intervening menus). |
NEXT FORMAT f2 | Go to next Input Forms Menu (skipping
any intervening menus). |
f3 | Not defined. |
REFRESH
f4 | Redisplay current menu in its initial
state before any specifications were entered, or existing specifications
were modified. |
PREV
f5 | Position to Previous Menu screen in sequence
of menus. |
NEXT
f6 | Position to Next Menu screen in sequence
of menus. |
MAIN/ RESUME
f7 | Request Main Menu or, if Main Menu displayed,
return to menu displayed when Main was requested. |
EXIT
f8 | Terminate REFSPEC and return to MPE control. |
|
| |
|
| NOTE: The function keys used by REFSPEC should not be confused
with the function keys defined for ENTRY (see Figure 2-2). Although
the two groups of keys are physically the same programmable keys,
their functions differ significantly. |
