Hi Keith,

And thus Keith let it be known to Peter:

  PL>> The function is called 'key' which is declared as a char,
  PL>> you send it two value parameters, validkeys and grebblevar
  PL>> of type string.

  KB> Yup, I do know _that_ much. ;)

Sorry.. I was just doing that for my benefit more than yours. :)

  PL>> Also, just to be picky, formatting your code makes things
  PL>> alot easier to read. It takes a bit more effort, but it's
  PL>> worth it in the end..

  KB> I thought I had. But it seems you're right...

There is good reason for formatting, when using utils like adding
breakpoints and then stepping over any offending piece of code, doing
things like splitting if..then..else statements as shown makes all the
difference when a programing is either stuck in a loop, or failing in the
intended responces it gives.

Damn.. I deleted that code snippet.. sigh..

Anyway someone else has replied to your question, prolly alot better than I
would have, since I was only trying to work it out to get more experience..
:) I'm a newby to pascal myself.

A function is used to return one value.  Regardless of the value, the name
of the function is actually what is returned when called.. other than that
it's like writing a procedure that only returns one value.  Therefore a
function will not have a var in it's header.. :)


Cya,

Pete
