!Program Design Description:
!Given the following data, write a program that counts the number
!of words before a zero value is reached.
!
!0x0005
!0x0004
!0x0002
!0x0003
!0x0001
!0x0000
!0x0010

!Program Solution:

org: 0x0000                !Start program here
loopCheck:
   load RI=[zero]          !Load array index with zero.
   load RB=[zero+RI]       !Load register B with zero.
   load RI=[wordCount]     !Load array index also wordCount.
   load RA=[data+RI]       !Load data[wordCount].
   add
   load RI=[zero]          !Load register I with zero.
   load [temp+RI]=RC       !Save data[wordCount] into temp.
   load RI=[temp]          !Put data[wordCount] into register I.
   jz endLoop              !Test data[wordCount] for zero.
   load RI=[zero]          !Set register I to zero
   load RA=[wordCount+RI]  !Load wordCount.
   inc                     !Increment wordCount by 1
   load [wordCount+RI]=RC  !Save wordCount
jmp loopCheck              !Next iteration
endLoop:
halt                       !Word tested as zero.  Halt program.
