David Epstein (david.l.epstein@gmail.com) is trying to use Stata's
programmable dialog system to create his own simple dialog box
to open a .csv file, but his dialog box isn't working:

I'll leave David's dialog box code under my signature below.

It looks like the "TEXT" line in the dialog box code is split
into two lines in the middle of the label().  If I copy David's
code and join these two lines to be one line

     TEXT     tx_dly      10  40   320  .,  label("Select file with data
   to be processed:")

then the dialog works as expected for me.

As an aside, if all David wants to do is present a simple file dialog to
prompt the user to choose an input file, and he doesn't want to put any
other options on the dialog box, then he may wish to look at
-help window fopen- and the example at the bottom of that help file.
