Summary: Missing escapes in vt100.h and window.c


Great program!  I am absolutely delighted with it.  I liked
the first version, but this is getting really good.

Here are my notes from last night.

There were errors in the shar file.  When I unshared, it I got
complaints about vt100.h and window.c .  Everything compiled
just fine, but the PF and arrow keys didn't work as they should have.

It later turned out that both vt100.h and window.c were missing
escape characters from some character definitions.  In vt100.h
look for the definitions of the PF keys.  Set the first character
in those strings to "\033".  It should be on line 173 which now
looks like:

    "OP","OQ","OR","OS",

Change it to look like:

    "\033OP","\033OQ","\033OR","\033OS",

In window.c wherever you see sendstring(, (I show them on lines
276 through 293), put an escape character at the beginning of
each string.  So, for instance line 290 which now looks like:

    case 0x4c:  c=0;  sendstring("[A"); break;

should look like:

    case 0x4c:  c=0;  sendstring("\033[A"); break;

Undoubtedly these escapes were at one time in the program but
were accidentally stripped out by an editor or through some
transfer process.  Putting them in there with the octal number
method (\033) helps prevent such accidents.

The vt100.doc file says that the program looks for 3 initfiles,
the first one being "initfile".  Not True, program only looks
for "vt100.init" and for "c:vt100.init".

When I first noticed that my vt100 arrow keys and PF keys weren't
working right, I tried to set them in the init file but somehow
that didn't work.  I was able to set the other variables in my
init file (except for cursor color which always remained blue).

I looked in init.c and couldn't see the problem.  I did see that
there are several instances where there was a constant integer 0
where a constant character '\0' should have been.  Changing
that didn't fix the problem with setting the function keys however.
Perhaps I'm doing something wrong or misunderstanding the documentation.
I did want to get this out early to spare any of you the troubles
I had with those escapes.

I used Xmodem to receive a file successfully.  I didn't try
sending and I didn't try KERMIT.

I used 48 lines successfully.  By setting the background to
000 and the foreground to 888 I could make the interlace
flicker almost unnoticeable.

I did have a little trouble with the go-away gadget while in interlace
mode.  It seems that the tip of my mouse pointer would have to be
somewhere beyond the center of the gadget.  Usually I use the tip of
my pointer, but in this case, I had to point with the center of my
pointer.  I also did have to fiddle with the screen and window drag
bars a bit to get the bottom line fully on the screen.

Still haven't tried the script capabilities.

For me this is the best free program I've ever had.  Now if Matt
will just hurry up with that new shell ...
