One or two factors have to be borne in mind when using a symbol table:

• Labels are partially case-sensitive. When looking-up the symbol table, Xplor8 searches first for

an exact case match, and returns the associated value if found, then makes a search ignoring

case. This allows you to have two labels with the same spelling, but different capitalization (if

your assembler can do it).

• In an assembly language program, more than one label may reference the same value. Xplor8

has no way of knowing which label is the correct one if such a value is encountered - it simply

picks the first label in the list which matches the given value.

• Labels longer than 8 characters will cause the output listing to become mis-aligned.

• Only 16-bit values are converted to labels, except in the case of the single byte representing

an address in page-zero memory when a Direct Address mode opcode is encountered.

The currently-loaded symbol file may be viewed by clicking on 'Symbol Table' in the View menu, or

using the keyboard shortcut: Ctrl+L
