Neil, No it is not the root folder. Is the PATH device written by Phil Borman. Basically it allows multiple locations to be transparently searched under a single name just like is done via the PATH statement in Windows.
This means you can open a file using a filename of the form PTH1_FILENAME and all locations associated with PTH1 will be searched for FILENAME. I would highly recommend using it.

Dave, Just reading the starting _doc file now and it is the sort of thing i needed to see first.... which leads me onto a something I've been meaning to ask for quite a while, if stightly off topic. What does pth1_ symbolize? My guess is thats it's the root directory on my HD but what is it's purpose? I'm reading through everyones responses, they are very useful. Cheers Neil >>> [EMAIL PROTECTED] 21 February 2007 17:08 >>> Neil, Did you try reading the STARTING.doc file? This is intended to get you started as quickly as possible. If you are already an experienced user then the QdosC68.doc file is likely to be of interest to see how certain OS dependent features have been mapped to QDOS. Most of the rest of the documentation is reference documentation. C68 is command line oriented as is normally the case on unix/Linux style systems. As you get more advanced you probably start use the make sub-system to avoid typing in command lines all the time. A full GUI system like Visual C does not make sense without an interactive de-bugger - something is that on the "wish list" for c68. In terms of editing - then yes any text editor will do. A simple text editor called QED is supplied on the runtime disks for those who do not already have one. However most users will have one for other purposes and you would normally continue to use your favourite. Regarding your hello world program in c68 you do basically just do: EX cc;'hello_c' -o hello.exe and this should create you an file called hello.exe. Omit the -o option and the binary file has the default name of a.out (again from unix legacy).

Hi Dave, I have C reference manuals and numerous books on the subject but as I sit in front of my QL I think, "Now, how do i use C68 to write that Hello world C program", by that I don't mean the source, i.e. #include <stdio.h> void main(void) { // I hope this is right ! printf ("Hello World"); } ... or whatever the correct syntax is. I mean, what do i do/use to enter the source ( i shan't assume i could use any text editor although i guess I can). how do i Link / compile... what gets generated etc etc etc. It's that which is a mystery to me as is all the numerous options i read about in the c68_doc. Amazed it wasn't PTR'izd with a rather friendly debugger thrown into the mix ;-) , although I have come across a front end screen that seems to link various parts of C68 together, perhaps thats my starting point. Cheers Neil p.s. I use Visual Studio 2005 Professional in work which deffo won't run in 4Mb ram ! >>> [EMAIL PROTECTED] 21 February 2007 15:34 >>> You are correct in that there is no document for those who are not already familiar with C. It was deemed a lot of work to write such a document and there are plenty of books around that already cover that. What is on the documentation disk is a guide to how C maps onto the QDOS environment. Also available is the detailed library reference material. Note that if anyone does provide any "getting started" type documents I am more than happy to add them to the standard set. I recently took early retirement, so if anything interesting comes up that might be c68 related I should now have free time to work on it. There have not been any developments in c68 for quite a few years now, but that does not mean that there are not a number of things that have not been identified that might be worth working on. Another thing that I have thought of working on is a port of gcc to the QDOS environment to replace c68. It would definitely not run on unexpanded QL systems as I would expect any system with less than about 4Mb RAM would be unable to run it, but would have the advantage of getting a maintained compiler onto QDOS/SMSE as well as supporting C++ facilities in addition to standard C. However it is not worth putting any effort into this if there would not be a reasonable demand for it.

Thanks for the link, I've stumbled upon that page already and it doesn't cater for the beginner. For example, there is source but i haven't found a ' beginners start here' section . As Phil Kett stated in an earlier email, I'm willing to learn but have hit a wall. I shall just play around with the executables I have on my hard drive and hope it all becomes clear.

There have been a coupls of 'introductions' to C68 in recent years. None of them seemed to continue beyond the initial episode. Mind you, I don't remember if this was intended to be a series (similar to say my Assembly language or Herb's Graphics) in QL Toady, or not. > Do i need to buy back issues of QL Toady or is there an idiots guide > already out there? Also, Is there a fast way of checking what version of C68 I I don't think it is worth your while trying to buy back issues of QL Toadt for a C68 Tutorial, but it might be very useful for other stuff ! I don't know/Can't remember how to find out the C68 version at present. With all the Assembly I've been doing, my C68 skills, not that I had many, are sadly slipping away .... Dave Walker's web site is the best place to go for C68, he's at : http://homepage.ntlworld.com/itimpi/index.htm And the latest version there seems to be 4.24f.
