One way to do this is to have myprog in source, and then start the
script like this:
#! /usr/local/bin/gforth /usr/bin/myprog
...
AFAIK Unix does not allow recursive use of the #! mechanism, so you
either have to do it in one level, as above, or myprog needs to be in
a binary format directly interpreted by the OS. Currently there is no
easy way to do this for Gforth programs (there is some way to make a C
file from an image, but it is not documented).
One other thing you could do is to write a small C program like this:
int main(int argc, char **argv)
{
return execlp("gforth",argv[0],"-i","/usr/bin/myprog.fi",argv[1],NULL);
}
(completely untested, and error checking should be added), compile that as
/usr/bin/myprog, and then use your original script.
