Cannot use 64th as a scripting language about sixtyforth

[drj11]

One way of achieving 2) is by defining the word #! to skip to the next LF, and requiring that all #! scripts use a space after the #!. There are other ways.

In order to do 1) we have to process argv. No idea what the binary protocol is.

[drj11]

a hint from some now forgotten Stack Overflow question led me to discover that the pointers are all on the stack, already in C's argc, argv format.

rsp will have been initialised to point to sequence of valid memory locations.

(NASM notation)

[rsp] is argc, the count of arguments, including the 0th argument (the name of the executable).

following (at increasingly higher address) are argc pointers, each pointer pointing to a C-style NUL-terminated string.

Following that is a NULL pointer (0x0).
