Re: [hylafax-users] faxcover.ps working for sendfax but not Cyphe us

[Curtis Rempel <Curtis.Rempel@corp.shaw.ca>]

Alan,

I based my procedure call syntax to BreakIntoLines on the message
http://www.hylafax.org/archive/1999-09/msg00148.php

sendfax seems to like it using this syntax, however, Cypheus does not.  

Bodo has indicated that the BreakIntoLines procedure sent from Cypheus is
identical to that from the default cover page.  This would seem to indicate
that the parameter syntax is correct, although, I can't really say for sure
as you know more about ps than I do.  ;-)  It would also seem to indicate
that something that Cypheus is doing/sending is incompatible.

I will do some more playing around with it to see if I can figure out
anything else.  Perhaps there are some ps gurus on the list that might be
able to see what is going wrong here.

Curtis

I must admit, I don't totally understand how BreakIntoLines is
working, and I haven't read the instructions.  But I think you might
be calling it with an incorrect parameter list, at least for the
version below.

> /wordbreak ( ) def
> /BreakIntoLines
> { /proc exch def
>   /linewidth exch def
>   /textstring exch def
>   /breakwidth wordbreak stringwidth pop def
>   /curwidth 0 def
>   /lastwordbreak 0 def
>   /startchar 0 def
>   /restoftext textstring def

To test, I added the following here:
restoftext foo

This causes the code to crash in gv and dump the stack, with
"restoftext" on the top of the ps stack.  It contains the number 300,
and not the comments "this is a comment" as I believe it should.  That
means textstring isn't being defined correctly, because it's not being
passed the correct parameters.

As far as I can tell from looking at the code, a correct call to
BreakIntoLines should look something like:

comments linewidth [a proc?] BreakIntoLines

I'm not sure what it's looking for, for "proc."  But it looks to me
like BreakIntoLines' last 3 parameters are as I showed above.

This may be of no use whatsoever, and I should probably RTFM before I
dig any deeper... but that's what I got from looking at the code and
playing around with it.  Hope it helps...

Alan
