LDC instruction
---------------
Earlier today I noticed the LDC pcode instruction seems to display
differently at times. Then I realized that it is operating with WORD
values and needs to have them aligned on an even BYTE boundary. For
example:
5004 B3 02 8C 3F CD CC
LDC. PUSH 02 WORDS
5017 B3 02 (02)8C 3F CD CC
LDC. PUSH 02 WORDS
