Hi,
DCL is a scripting language for OpenVMS, whose lines of code must all
start with a $.
Here is a code excerpt (from
http://www.eight-cubed.com/articles/dcl_standards.html):
| ||$ on warning then goto nopriv
$ set on
$ set process/privilege=(sysnam,sysprv)
$!...
$nopriv:
$ write sys$output "Required privs: SYSNAM, SYSPRV"
$ status = 36
$ goto exit
$!...
$exit:
$ set process/privilege=(nosysnam,nosysprv)
$ exit status + (0 * f$verify (old_verify))

Is there any clever way that the following features could work with
this kind of code?
1) dap (delete a paragraph): this currently deletes the whole source
file - because there are no empty lines between paragraphs (an "empty"
line must contain at least the $)
2) >> (indent a line): this indents the leading $ as well as the rest
of the line; instead, the dollar should stay in column 1, and only the
rest of the line should be indented
3) J (join lines); gqq (format the line): if multiple lines become one
line, or vice versa, the dollars are not removed/inserted as they
should be
What I have come up with so far is using 'comments':
:set comments=:$
This at least puts the $ sign on each new line.
I suppose you could have a pair of maps; one of which removes all the
leading "$"s, and the other would put them back:
map <F4> :%s/^\$//e
map <s-F4> :%s/^/$/e
Furthermore, you could automate this if you're confident enough in their
effects:
au BufRead * if &ft =~ "dcl" | :%s/^\$//e|endif
au BufWrite * if &ft =~ "dcl"|:s/^/$/e|endif
You might wish to put these into a .vim/ftplugin/dcl.vim file (I'd have
to guess at the actual OpenVMS directory, perhaps
[wherever.vimfiles.ftplugin]dcl.vim ?).
Of course, these are untested.
