Tasking problem

[Andrew Holt]

Hi,

I have just built the current git version of gforth (Gforth 0.7.9_20191107)
and tun a simple tasker test.

I get the following error message:

in file included from *the terminal*:0:-94575174554671:
in file included from *the terminal*:-1:1:
in file included from /tmp/tasks.fth:2:9:

It looks like I need to include something else in my simple test (BTW this
woks in the release on ubuntu):

require tasker.fs

variable cnt1
variable cnt2
-1 value t1
-1 value t2

0 cnt1 !
0 cnt2 !

: delay ( n -- )
    0 do 1 ms pause loop
;

: task1 ( str len -- )
  100 NewTask dup to t1
  0 swap pass
  begin
        ." task1:" cr
        10 delay
        1 cnt1 +!
        pause
  again
;

: task2 ( str len )
  100 NewTask dup to t2
  0 swap pass
    begin
        ." task2:"
        cnt1 @ . cr
        pause
    again
;

: main
    s" task1" task1
    s" task2" task2
    begin
        pause
        single-tasking?
    until
;

\ main


Any tips ?
