i sent the command like:
Code:
ARRAYWRITE speed [dec var1,dec2 var2,0]
having that it was not possible to use speed as word.
makes no sense to me

ARRAYWRITE speed

speed must be an existing chr array big enough to contain the text generated plus a null terminator
a word var could hold only 1 chr safely ,since pbp checks nothing anything could get clobbered by misuse like that
