     Syntax: name
 
     A "symbol" is a name that represents a register, a segment address,
     an offset address, or a full <segment>:<offset> address. At the
     source level, a symbol is a variable name or the name of a
     function. Because symbols follow the naming conventions of the
     C compiler, C symbols are case sensitive when given as arguments
     to CodeView commands unless the Case Sensitivity option is
     turned off.

          Options (O) Command-Window Command
 
     In assembly-language output or in output from the Examine Symbols
     (X?) command, CodeView displays global labels (such as procedure
     names) with a leading underscore. For example, the function main
     is displayed as _main. You don't need to include the underscore
     when specifying such a symbol in CodeView commands.
 
     Labels (for example, __chkstk) within library functions are
     sometimes displayed with a double underscore. You must use two
     leading underscores when accessing these labels with CodeView
     commands.
