Hi Chip,
thanks for the suggestion. Unfortunately, this will not work because
of line
continuations, which look like this:
$ write sys$output "some text ", "more text ", -
"even more text ", -
"and yet more"
$ write sys$output "next bit"
In other words, there may be lines with no leading $s. The <s-F4>
mapping would
tend to put "back" the leading $s even on lines which did not have it
in the
first place (lines 2 and 3 above).
Line continuations, i.e. lines with no leading $, are always preceded
by a line
ending with a "-" (hyphen), as seen in the example above. One could
rely on
this, perhaps, to detect that lines 2 and 3 in the excerpt above
should get no
leading dollar. However, I think you can have lines ending with a
hyphen, which
do not mean a line continuation, so this would not work either. (I am
not
totally convinced about this, but I seem to remember something like
that.)
But your idea is exactly what I am thinking: if only vim could somehow
ignore
the leading $, ignore that it is there, and process all commands as if
the
dollar was not there...
Thanks,
Sam
