Wish list: 'gosub' functionality

[pevama]

Thanks for a great start at providing a tool to allow TP programs to be written using a modern language structure.

The ability to call a 'subroutine' and return would greatly improve structure and readability. I imagine that the return could be implemented by the 'gosub' loading the return label value into a specified register. If a different register were used for each subroutine then nesting of 'gosubs' would be possible.

Hi there,

Thanks for your comment.

The ability to translate UFRAME_NUM=[value] would be very useful as I frequently need to switch frames in my work.

If I recall correctly, there's the 'set_uframe()' method along with 'set_utool()'. Unfortunately the example is missing a few things. Please have a look through the tests, which should be a bit more comprehensive: https://github.com/onerobotics/tp_plus/blob/master/test/tp_plus/test_interpreter.rb

I agree. I actually supported this sort of feature in some very early TP+ prototypes, but it did not make it into the current version. Memory management essentially was out of scope.

I've been meaning to do a large scale rewrite in Go that incorporates some of these ideas, but I haven't gotten around to it. I'm happy to accept pull requests here though ;)

time flies.... 😨

turns out the use_utool and use_uframe methods are implemented.

still need subroutines/functions/methods though.
