1. Getting Dialog Button Results?
I'm new at Euphoria (like 1 week), but I like how you can easily edit and
compile an .exe file, with fairly straightforward language.
To learn, I took on a project at work to store data in a database, using a
form in a DOS window.
I am trying to modify the mydata.ex program to do this, using David Cuny's
routines for dialog boxes. I have been successful in creating different
modules that work OK by themselves, and a "form", really a large dialog box
with SLE fields, default values passed into the function, labels, and a few
special buttons on the bottom.
My problem is, I can't figure out how to use the results of the button click
used to exit the dialog procedure. David's examples end by printing out
"you exited with: New" where New is my button name. However, I want to use
this button click to decide what to do next.
I've tried assigning a variable to the result[1], and it prints with no
problems, but I have been unable to get a "If result[1]="New" type of
statement to work.
Am I doing this correctly, or is the syntax wrong? Is it something to do
with the result being stored as ASCII? How do I use the results David's
button click routine to branch off where I want?
Any help would save my sanity!

I think you are looking for
if compare(result[1], "New") = 0 then
OR
with version 2.1
if equal(result[1], "New") then

You can't use "=3D" in a comparison with a string; you have to use
the compare() function:
if compare(result[1],"New")=3D0 then
blah, blah, blah
end if
compare() returns -1 if the first argument is less than the
second argument, 0 if they are equal, or 1 if the first argument
is greater than the second argument.
"=3D" applied to strings (sequences) returns a sequence of 1s and
0s where each element is a 1 if the corresponding elements in the
two sequences are the same, and 0 if they are not. So,
"ABC"=3D"aBC" will return a sequence {0,1,1}. Sequences are not
valid for IF tests, so your program bombs.
