Commands
SYMBOLSymbol Name Management
Usage:SYMBOL <symb> <-a symb value> <-r symb> <-c|l|s>
The SYMBOL command adds or removes symbol names from the symbol table. If only a
symbol name is provided to the SYMBOL command, then the symbol table is searched for
a match on the symbol name and its information displayed.
The -a option adds a symbol name and its value into the symbol table. The -r option
removes a symbol name from the table.
The -c option clears the entire symbol table, the -l option lists the contents of the symbol
table, and the -s option displays usage information for the symbol table.
Symbol names contained in the symbol table are truncated to 31 characters. Any symbol
table lookups, either by the SYMBOL command or by the disassembler, will only use the
first 31 characters. Symbol names are case-sensitive.
Symbols can also be added to the symbol table via in-line assembly labels and ethernet
downloads of ELF formatted files.
Examples:
To define the symbol “main” to have the value 0x00040000, the command is:
symbol -a main 40000
To remove the symbol “junk” from the table, the command is:
symbol -r junk
To see how full the symbol table is, the command is:
symbol -s
To display the symbol table, the command is:
symbol -l
