DIR

Syntax	Description
DIR	Displays symbol names for the current module.
DIR \module	Displays symbols of module.
DIR \module LINE DIR \module\func LINE	Displays line number information for the current or specified module or function.
DIR \module\func	Displays symbols of function func contained in module.
DIR BFUNC	Displays the names of all predefined µVision3 functions.
DIR DEFSYM	Displays the names of symbols created with the DEFINE command.
DIR FUNC	Displays the names of all µVision3 functions.
DIR LINE	Displays line number information for the current module.
DIR MODULE	Displays the names of modules in your target program.
DIR PUBLIC	Displays the names of all global symbols.
DIR SIGNAL	Displays the names of all user-defined signal functions.
DIR UFUNC	Displays the names of all user-defined functions.
DIR VTREG	Displays the names of all CPU-pin registers that are supported by the CPU driver.

Use the DIR command to display various types of symbols. When DIR is invoked with no additional arguments, the symbol names of the current module display. The current module is the module whose address space is indicated by the program counter ($). µVision3 determines the address areas assigned to the module when the target program loads.

µVision3 maintains various internal symbol tables whose contents can be displayed using the DIR command with its various options.

DIR Command Option	Description
\module \module\func	Displays the symbols of the specified module or function are output.
BFUNC	Displays the names of predefined µVision3 functions. These functions are always available and cannot be deleted or redefined.
DEFSYM	Displays the symbols created using the DEFINE command. Refer to DEFINE for more information. Using this option, the output of the symbols created by the 'DEFINE « type »« name »' command is permitted.
FUNC	Displays the names and prototypes for all currently defined µVision3 functions. This includes: predefined functions, user-defined functions, and signal functions. Note that µVision3 functions are not the same as functions in your target program.
LINE \module LINE \module\func LINE	Displays line numbers for the current module, the specified module, or the specified function.
MODULE	Displays the names of all modules in your target program. The target program must be loaded.
PUBLIC	Displays all global symbol names. These objects have the attribute PUBLIC in assembly language. Non-static C variables are also included in this group.
SIGNAL	Displays the names of signal functions. Signal functions are user functions that process in the background. These are used to produce signal forms for the port inputs.
UFUNC	Displays the names of µVision3 user functions. User functions are those function defined by the user.
VTREG	Displays the names of CPU-pin registers supported by the currently selected CPU form the device database.
