<div>https://github.com/Krush206/3bsd-csh/commit/726de5d</div>
I wanted to diverge the 'function' built-in from 'goto', so I applied a limitation so that labels must have an 'exit' to their end.<br>

<div>
<div>Fixed the variables bug. Now is possible to modify variables globally.<br>

<div>I made it. I didn't test thoroughly, but I can tell it's limited. It doesn't work well off sub-shells. Variables defined in function calls are visible only to the called function (this resembles C in some way).</div>
<div><br>
</div>
<div>In the meantime, I'll figure out how to solve the bugs. That's what I have for now.</div>

<div>Passing variables by value is achieved by sourcing from a sub-shell. Passing variables by reference is achieved by sourcing from the parent Shell. Command substitutions always pass variables by value, though.</div>
<div><br>
</div>
</div>
<div>I'm thinking of introducing a built-in 'function' command based on this idea. Any thoughts on that?<br>
</div>

</div>
<div>By the way, regarding the exit status issue I reported on Csh, it was a problem on my side. My mistake. Sorry about that.</div>

This is much better than aliases in scripts. Works for Tcsh and Csh.</div>

One problem I found on Csh is the exit status output is never stored to the parent Shell.</div>

For the function workaround described above, the workaround to store the exit status is to echo:</div>
