I hope (famous last words!) that this tool will play nicely under USS as it just has a command-line interface with an input file and an output file, so the compile might be the sticking point.
I downloaded the Graphviz tarball, uploaded it to USS and unzipped it (using your tool) and un-TAR’d it and ran the CONFIGURE scrit. That failed due (I think) to the x’05’ ‘tab’ characters which I edited and changed to x’09’. It failed again with
./configure 227: FSUM7332 syntax error: got Word, expecting )
I’d really like to get this working - especially to help raise the profile of the mainframe within my company and to show what it’s capable of - if you could help me get this working I’ll donate $50 to a charity of Rocket’s choice (this is not a joke!)
