Where is it? Your current directory is not checked for executables in most shells, unlike that toy o/s MS-DOS. If there isn't a PATH to it, you will definitely have to specify ./filename
Thanks, all, for your interest. Apparently my previous post to the list was not delivered to the list because Simon Roberts's reply had a reply-to header to his id.
I have since been able to successfully run many programs using ./filename, but I do wonder why the current directory is not checked. What is wrong with that behaviour? And why should the DOS shell be derided for providing this facility?
PWD may or may-not be in the path of the user. *nix checks the path first, DOS checks the path and the current directory. (I do mean checks, as DOS is still being used today, I've run 4 CNC machines that boot DOS, 2 MS-DOS and 2 DR-DOS). I did a man exec and it seems to be a bash script executor, IIRC you had compiled the program in the original question, what impact could exec have in this situation?
