Volker,

>>copy/part B back tail b

>>back tail b
... yes , and what does the last BACK TAIL B evaluates to? an INDEX
position?
Simply restated, I would like to understand why BACK TAIL B used alone like
here:
>>BACK TAIL B
returns a series
while when used in:
>>copy/part b BACK TAIL B
it returns a number. (I assume it returns a number because this is what
COPY/PART needs as a second argument)
Many thanks,
JF
