I have a Windows program where I am checking several fields and if the fields
are not entered, I want to tell the user to input the data in the field and then
proceed to the next field. If the user does not like what he has entered he can
change it and leave the other fields as entered. I have these several input
statements in a procedure. If the field needs to be entered the program seems to
return to the starting point at the beginning of the procedure, and does not
return just to the statement being executed. Is this is what is happening, or is
there a way to force it to return to the statement?

You'll have to show us the code for the procedure you mention above.
It's a bit confusing, since there shouldn't be any "input statements" in
a Windows program.
In general, however, you should check the fields when the user
leaves the last field, or better, when she clicks on an "OK" button,
signifying that all the necessary data has been entered. Your validation
routine checks the contents of each entry field, and if invalid, sets focus
to that field (and perhaps opens a message box explaining what needs to
be done).

jvandal,
The following demo isn't exactly what you specified, but it's close & maybe
a start:
-- CODE STARTS:
-- code generated by Win32Lib IDE v0.10.6
include Win32Lib.ew
without warning
----------------------------------------------------------------------------
----
-- Window Window1
global constant Window1 = create( Window, "Enter info into each field, press
finished", 0, Default, Default, 400, 300, 0 )
global constant StatusBar9 = create( StatusBar, "StatusBar9", Window1, 0, 0,
0, 0, 0 )
global constant EditText2 = create( EditText, "", Window1, 24, 20, 50, 20,
0 )
global constant EditText3 = create( EditText, "", Window1, 120, 20, 50, 20,
0 )
global constant EditText4 = create( EditText, "", Window1, 212, 20, 50, 20,
0 )
global constant EditText5 = create( EditText, "", Window1, 28, 68, 50, 20,
0 )
global constant EditText6 = create( EditText, "", Window1, 124, 68, 50, 20,
0 )
global constant EditText7 = create( EditText, "", Window1, 216, 68, 50, 20,
0 )
global constant PushButton8 = create( PushButton, "Finished", Window1, 104,
116, 90, 30, 0 )
----
procedure PushButton8_onClick ()
if length(getText(EditText2)) = 0 or
length(getText(EditText3)) = 0 or
length(getText(EditText4)) = 0 or
length(getText(EditText5)) = 0 or
length(getText(EditText6)) = 0 or
length(getText(EditText7)) = 0 then
setText(StatusBar9, "Please enter data into all fields")
else
setText(StatusBar9, "ok")
end if
end procedure
onClick[PushButton8] = routine_id("PushButton8_onClick")
WinMain( Window1, Normal )
-- CODE ENDS

Is this is what is happening, or is there a way to force it to return to the
statement?
