14.2.2 Symbol Table

If only the l (letter) option is specified, and not the c or s options, when the assembler is invoked, the assembler will output a symbol table to the list file after the machine language code section.

If the c option is specified, a cross-reference table will be output instead of the symbol table. The symbol table outputs the name, value, and type of every symbol in the source file. It has the following format.

Symbol Value		Supplemental	Symbol Type	Symbol Name
		Information
		*	A
00000000			T	XXXXXX
	+		U
	-		D

Symbol Value

Supplemental Information
