Re: %LEN and *ZERO

["Peter Dow" <pcdow@xxxxxxxxxxxxxxx>]

Hi Barbara,

Assuming that you were referring to *LOVAL in relation to %len, I would
assume that %len is considered an unsigned integer, in which case your
statement "*LOVAL means the same as zero" is correct. However, when doing
EVAL X = *LOVAL where X is a signed number, *LOVAL is a negative number.
