The message box is an amazing feature. You can use it in a debugging
session to work with the state of your code at the breakpoint.

There is a gotcha to be aware of here.
Checking if a previously unused variable is empty returns false. That
has caught me out a few times. I wonder why the answer is false. I
think the engine interprets the variable as a string instead, in the
same way that 'answer hello' without quotes around
Wait. I don't get this. You saying that checking if an unused variable is
empty returns false? Does revolution put some data in a variable when
created?

Sort of, but only in specific cases, which is mostly a side-effect of
how friendly Rev's interpreter is and how it deals
By the way, off topic a bit:
Wouldn't I am be the same as I am? ((notice the space after
I in the second example)).

Certainly should be the same. Isn't it? It is for me with 3.5.

Stephen,
Without even checking, since it's the way it would be done in HC, just
use:
if tUsername is empty then
if tUsername exists then ...
You were already there. Didn't you check these out in the messagebox?

Hi Stephen,
Search the docs for empty. It will show you things like
put empty into x
set the cProp to empty
So, you will also want to read up on put and set.
There is also a function variableNames, which will probably be very
useful to you. Why do you want to check for the existence of a
Lol. Of course. I knew it would be easy. Thanks.
For the life of me I could not find an example in the docs; the user guild
or online.
The messagebox? I hardly use it. Gets in the way mostly. I've been using it
to look at global variables. I know you can run commands. But if you don't

Stephen, I should have checked. Check exists in the dictionary for
the rev syntax. Not quite as straightforward or easy as with HC.
Sorry,

I did search for empty in the Online Dictionary. But all I got were
property keywords. I also read the docs on put and answer and saw nothing
about empty.
Anyway know now, thanks.
As for checking for existence of variables.. Just a habit I formed over
years writing dbase and c. Always check the
Ahhh! Exists was there. I was looking at it from the wrong end. Thanks.
God I feel like I have to unlearn all my coding habits and thinking.

Hi Stephen,
How do I check if a variable is empty? Sort of like;
If !empty(tUsername)
// process here
Endif
Empty() is a Foxpro function that pops if what you are checking is
empty. I
can¹t seem to find it¹s equivalent in revolution. Am I approaching this
the
wrong way? And can I

on Strict Compilation (and I have) but I¹d rather have the assurance of

It is a non-issue. Rev does not require you to declare
