"0" is a string not a character, in asciiz it would be: '0', '\0' .
Assembly does not directly support strings, however see the DW 
assembler directive which allows you to define asciiz style strings.
The DW directive is defined in section 3.2 "Text Strings" of the
"MPASM Assembler, MPLINK Object Linker, MPLIB Object Librarian User's Guide"
from Microchip (DS33014). Constants are defined in section 3.4 .
