[Bayonne-devel] many forms of labels

[David Sugar]

At one time we had a lot of forms of duplicitive synonyms and ways of 
setting labels.  There was the ::xxx method.  There were "proc(edure)" 
and "service", and there was private and public.  There may have been a 
few others!  On the 1.0 ccscript3 I did purge all but the most logical 
ones.  Hence:

private xxx
        label local to a script

public xxx
        label globally accessable from any script using yyy::xxx form

program xxx
        label globally accessible, with options, special use case.  With
        "program main" being the primary special use.

function xxx
        parametric function, globally callable from any script, called
        from call statement

local xxx
        same as function, but only accessible from the same script file
        commonly used to build local macros

I am hoping that is all the special label cases that now exist in 
ccscript3 1.0.

Calling labels:

        goto
                to goto a public or private label, can set vars...

        call
                to call a function, creates new stack context

        source
                to call a label using current stack context, kind of
                a subroutine call but uses same local vars...

        gosub
		to use a public or private label and create an entirely 			new base 
context

        return
                returns from a source, call, or gosub
