I have no particular insights, but ISTM that since it is possible to
SET PROCESS/PARSE=EXTENDED with ODS5, then this may guarantee a match.
SET PROCESS/PARSE=EXTENDED on it's own will preserve case but will access
files in a case insensitive manner.
SET PROCESS/CASE_LOOKUP=SENSITIVE
would be needed to do case sensitive file accesses.
But then they could have just written the commands in
uppercase
ie
RUN SYS$SYSTEM:TCPIP$SMTP_RECEIVER.EXE

Found this jewel in the SYS$SYSTEM directory:command,
$ run:
$ run 'f$edit("sys$system:tcpip$smtp_receiver.exe","upcase")'
Since this is written supposedly by people part of VMS engineering (or
perhaps "formerly part of" due to downsizing), I have to ask if there is
any justification for the above from a DCL/VMS engineering point of view.
Also found
$ set :=
Is this a strict equivalent to DELETE/SYMBOL/LOCAL SET ?
Another qestion: the same command procedure that has the fancy run
also has this:SYS$SYSTEM:)
$ serv_id = f$edit("tcpip$smtp","upcase")
$ serv_home = f$edit("sys$specific:[''serv_id']","upcase")
(these constructs are used in the TCPIP$*.COM files throughout
ways.
Were these files generated using some DCL generation tool that perhaps
converts the Tru64 scripts ?
I keep wondering why the TCPIP engineers wrote those procedures in those
