Comment (by Vhati):

 * gloryInv (global9) is a collection of inventory items. "global9 at: 4"
 is theRations.
 * "proc0_4(n)" - Tests the given plot flag.
 * "proc0_2(n)", "proc0_3(n)" - Not clear on what they each do, but
 definitely setters.

 script 16 has a procedure to cleanup mainIconBar (global69) when it sets
 amount to 0 on an item.
 {{{
