Hello everybody,
I have been asked to implement an application (FRED) under ALL-IN-1.
FRED accesses RALLY and then it disappears in its own world. The user
interface is provided by about 20 pages of DCL which writes escape
sequences to the screen to paint nice menus and accept user input.
The problem occurs at the following line:
$read/end_of_file=end/prompt= -
"''esc'[20;40H''esc'[KEnter Choice:__''esc'[2D" -
sys$command CHOICE
DCL-E-nnnnnn, File has not been opened by DCL - check logical name.
FRED runs hapily started form the dollar prompt and even spawned from
DCL. From under ALL-IN-1 it doesn't.
I have redefined sys$command to sys$input and even defined sys$input to
the translated logical sys$output To no avail apart from making it
worse.
Is there any way I can get round this problem without touching the DCL
code and without asking ADG to rewrite their application so it's
ALL-IN-1 compatible?
Thanks in advance.
Wivine. (IS Service Center Brussels - DTN 856-7558)
P.S.: This note has also been posted in the ALL-IN-1_CLI notes file.

Note 221.1 SYS$COMMAND and ALL-IN-1 sub-process 1 of 1

re: .0
I guess the problem probably derives from the fact that during
sub-process execution of a command procedure SYS$COMMAND is defined as
the mailbox device rather than the terminal. You could try defining
SYS$COMMAND to SYS$ERROR or SYS$OUTPUT (which should be pointing to the
terminal) at the beginning of the procedure, or in a jacket procedure,
and then deassigning it at the end.

| 2825.2 | Try SPAWN | MIMS::HUSSEY_D | NOT the MAMA!!! NOT the MAMA!!! | Tue Jun 08 1993 17:06 | 7 |
If you aren't passing things back and forth from ALL-IN-1 (based on
fact tha you don't want to change the DCL that works outside of
ALL-IN-1), use the SPAWN function rather than COMMAND. This will
create an honest-to-goodness VMS subprocess rather than the ALL-IN-1
captive subprocess.
FWIW...
