SHOW SYMBOL
SHOW SYMBOL
Displays the hexadecimal value of a symbol and, if the value is equal to an
address location, the contents of that location.
Format
SHOW SYMBOL [/ALL] symbol-name
Parameter
symbol-name
Name of the symbol to be displayed. You must provide a symbol-name.
Qualifier
/ALL
Displays information about all symbols whose names begin with the characters
specified in symbol-name.
Description
The SHOW SYMBOL/ALL command is useful for determining the values of
symbols that belong to a symbol set, as illustrated in the examples.
Examples
1.
SDA> SHOW SYMBOL G
G = 80000000 : 8FBC0FFC
The SHOW SYMBOL command evaluates the symbol G as 80000000
16
and
displays the contents of address 80000000
16
as 8FBC0FFC
16
.
2.
SDA> SHOW SYMBOL/ALL BUG
Symbols sorted by name
----------------------
BUG$BUILD_HEADE 80002038 => 24A89F16 BUG$_CONSOLRX50 00000640 => 10A2020E
BUG$DUMP_REGIST 80002040 => 24A89F16 BUG$_CONTRACT 000000C0

BUG$TABLE 8000D09E => 00280001 BUG$_CWSERR 00000698 => 004C414E

This example shows the display produced by the SHOW SYMBOL/ALL
command. SDA searches its symbol table for all symbols that begin with the
string ‘‘BUG’’ and displays the symbols and their values. Although certain
values equate to memory addresses, it is doubtful that the contents of those
addresses are actually relevant to the symbol definitions in this instance.
