[comp.os.vms] DCL continuation lines

pritchard%cuavax.dnet@NETCON.CUA.EDU (Hugh Pritchard/Systems Programming) (07/14/88)

One of our consultants found this quirk in the display of DCL 
continuation prompts; I was unable to explain it.  Can anyone
help explain it?

Quirk:

Normally, the prompt for a continuation of a DCL command (command line 
ending in a hyphen [-]) is the existing prompt preceded by an underscore
(_).

$ command stuff -
_$ more stuff

This works for real commands and symbols which translate to (most) real
commands, but not symbols which translate to "@...."  For these symbols,
the continuation prompt is the same as the ordinary prompt! 

$ some_symbol == "@some_com_file"
$ some_symbol stuff -
$ more stuff	!Note absence of preceding underscore!

Everything seems (?) to work properly, but the absence of the underscore 
is unnerving.
