I have a few questions on using 4th Dimension; I'm using 2.1.1.

1) Double clicking in an empty region of an included file brings up a 
programmer-definable input layout for entering a new record.  This is a 
useful interface property.  Unfortunately, 4D stays in an infinite record 
input loop until the user selects "Cancel".  I have found that users are 
confused by this, particularly since they get no acknowledgment that 
their record was entered (except that the fields in the layout are 
cleared).  I want the program to return to the original layout in 
response to either a save or a cancel (i.e., add only one record in the 
included file).  Is there any way to do this?

2)  I understand that the scripting language does not include message 
passing capabilities (such as Hypercard objects have).  Nevertheless, I 
have encountered several cases where it would be useful to execute 
object scripts from procedures.  Can this be done?

3)  I would like to integrate bar code printing and reading into a 4D 
database used for inventory and shipping control.  Does anyone have 
experience with bar codes and 4D?  Since the data is for internal use 
only, no special codes (e.g., UPC) are required.  I presume I just need to 
add a font in order to do the printing part.  Are there any freeware bar 
code fonts?  The input side might be a little tougher.  Can a bar code 
device (presumably attached via the ADB) be easily interfaced with 4D?  
Can anyone recommend a particular vendor?  

4)  Has anyone used the 4D front end available from Natural 
Intelligence?  I think it got pretty good reviews in one of the popular 
trades, but some independent verification would be reassuring.


Thanks.
