| - | **$GS-TOOLCALL** ( i*n i t1 j t2 tool# -- j*n ) call Toolbox, passing i arguments to the tool, and receiving j results. t1 and t2 are the type bits for the arguments and results, respectively, where b0 = the first arg, b1 the second arg, etc. A 1 bit means the argument or result is a long, 0 indicates a word. Arguments and results are specified/received in reverse order from the toolbox call (first off the Forth stack is first on the return stack). | + | **$GS-TOOLCALL** ( i*n i t1 j t2 tool# -- j*n ) call Toolbox, passing i arguments to the tool, and receiving j results. t1 and t2 are the type bits for the arguments and results, respectively, where b0 = the first arg, b1 the second arg, etc. A 1 bit means the argument or result is a long, 0 indicates a word.
