RE: SBMJOB inserting nulls

["Metz, Zak" <Zak_Metz@xxxxxx>]

Putting the * in 101 forces it to pass ALL 101 bytes, instead of
truncating off trailing spaces and only passing the "real" data, which
means you get the garbage in the rest of the variable. The key here is
that the system is truncating trailing blanks when the variable is
larger than 32 bytes. The * prevents that truncation.

Another method is to pass the length of the "real" data in a separate
variable, but that information is not always readily available.
