Sounds about like the way IBM's JCL from OS/360 and successors works.

You can split a statement after a comma in most cases, and continue
it on the next line, after the usual // and some spaces.

I believe the original (early) versions had a more usual system
with a continuation character in column 72, and then start the
next statement in column 16. I presume it was found hard to get
right so they changed it.

I believe that there are a few other languages with a similar
continuation method. That is, if you end a statement in a legal
end, no continuation is needed.
