### Problems with Personl Tex Inc's ptips program ?

I am having problems using special commands of the form
\special{ps:figure.ps}
in Personl TeX Inc's ptips DOS program (version 2.5) which
converts dvi to postscript.
Sometimes it works and other times I get the warning message
<<unable to open graphics file [figure.ps]>>. This does not
happen if the special command occurs in the first 2 or three
pages of the document, so it can find the file,  but if I move
it to a later page I get the message.

I do not have these probles with the same files under Unix
using another dvi to ps program.

I'm searching for a converter, which converts C sources to TeX or LaTeX.
Anybody out there who knows a converter, so please post on me.

Also i'm searching a converter bourne shell to TeX/LaTex.
