I'm maintaining a GUI written in PVWave running under Open VMS
(No, this wasn't my idea)
Anyways, I'd like the operator to be able to look at a small ASCII
file in a text window, modify it, and save it. Not too tough, eh?
Let's say the file is named foo.dat and t looks like this:
1234
abc
9
lmnop
So, I use WWText with File='foo.dat', col =...
Sorta like this:
TextWin = WwText(Wid,
File = 'foo.dat',
cols=10,
rows=4,
font=...)
This pops up a nice text window showing the operator the file.
The operator can click in this window and change the text using the
keyboard. So far so good.
Now, I need to get the altered text back out of the window and
write it to the file.
So I use:
Text = WwGetvalue(Textwin)
The string Text now contains the value:
1234(lf)abc(lf)9(lf)lmnop
Where (lf) is a linfeed sans carriage return.
If I do a
printf, outunit, Text
where outnunit is the file unit I get:
1234
abc
9
lmnop
Whereas I want:
1234
abc
9
lmnop
WHat should I do? Formatting the print statement is not an option
because the record lenght (and number of records) may be different
after editing. Is there anyway I can substitute a carriage
return/linfeed for the linefeed? Or can I somewhow WwGet the value of
the WWText widget into an array?
I don't wnat to use WwTable, because the operator would have to remember
to enter <return> on each cell they edit, and would likely forget to do
that (I know I would).
So, what the bloody 'ell should I do?
