JZZERO - zero the down call bank

When filling the down call bank for the next processor to be called it is safer to clear the unused part of this bank to zero, with

CALL JZZERO (NL, ND)

with     NL  leave the links 1 to NL untouched and reset links
             NL+1 to the end to zero;
         ND  same for the data words, words 1 to ND untouched.

Note that JZIN does already clear the new down call bank to zero.
