Hi,

on top of all the good tips you received here some remarks:

1) sure hope this is for testing only as the use of a file m.text in your application is a showstopper. Never ever use a oneletter file and surely donot use the "m"
2) not completely sure why about your coding suppose you only wrote this for yourselve to proof the the (memo)field in question does not have the value you expected. If that is the case I would recommend you to make use of the debugger.:
start up the degugger
start your program
set in the watch windo the field you are interested in
step through your coding and watch the value of that field.

Hope this helps you.

Regards,

Koen
