Howdy,
I am talkign to Perry at PDX Hackathon, and the example code that does
not work should be:
.include 'errors.pasm'
.sub main :main ### :pedantic_args
.param string argv :slurpy
errorson .PARROT_ERRORS_GLOBALS_FLAG
push_eh myhandler
$P0 = find_name "i_better_not_exist_or_this_thing_is_crazy"
pop_eh
if null $P0 goto wasnull
say "not null, must have existed somehow. inconceivable!"
exit 1
wasnull:
say "was null. not good!"
exit 2
myhandler:
pop_eh
say "generated exception. excellent!"
exit 0
.end
Note that errors.pasm had to be included, errorson does not have
parens and a few pop_eh's need to be sprinkled in.
