Command Summary
The following table lists the commands that are available for the LIBx51 library |
10 |
manager. The usage and the syntax of these commands are described in the |
|
sections that follow. |
NOTE
Underlined characters denote the abbreviation for the particular command.
LIBx51 Command |
Description |
ADD |
Adds an object module to the library file. For example, |
|
LIB51 ADD GOODCODE.OBJ TO MYLIB.LIB |
|
adds the GOODCODE.OBJ object module to MYLIB.LIB. |
CREATE |
Creates a new library file. For example, |
|
LIB251 CREATE MYLIB.LIB |
|
creates a new library file named MYLIB.LIB. |
DELETE |
Removes an object module from the library file. For example, |
|
LIBX51 DELETE MYLIB.LIB (GOODCODE) |
|
removes the GOODCODE module from MYLIB.LIB. |
EXTRACT |
Extracts an object module from the library file. For example, |
|
LIB251 EXTRACT MYLIB.LIB (GOODCODE) TO GOOD.OBJ |
|
copies the GOODCODE module to the object file GOOD.OBJ. |
EXIT |
Exits the library manager interactive mode. |
HELP |
Displays help information for the library manager. |
LIST |
Lists the module and public symbol information stored in the library file. |
|
For example, |
|
LIB251 LIST MYLIB.LIB TO MYLIB.LST PUBLICS |
|
generates a listing file (named MYLIB.LST) that contains the module |
|
names stored in the MYLIB.LIB library file. The PUBLICS directive |
|
specifies that public symbols are also included in the listing. |
REPLACE |
Replaces an existing object module to the library file. For example, |
|
LIB51 REPLACE GOODCODE.OBJ IN MYLIB.LIB |
|
replaces the GOODCODE.OBJ object module in MYLIB.LIB. Note that |
|
Replace will add GOODCODE.OBJ to the library if it does not exist. |
TRANSFER |
Generates a complete new library and adds object modules. For example, |
|
LIB251 TRANSFER FILE1.OBJ, FILE2.OBJ TO MYLIB.LIB |
|
deletes the existing library MYLIB.LIB, re-creates it and adds the object |
|
modules FILE1.OBJ and FILE2.OBJ to that library. |

380 Chapter 10. Library Manager
Creating a Library
The CREATE command creates a new, empty library file and has the following format:
CREATE libfile
10 |
|
libfile is the name of the library file to create and should include a file extension. |
|
|
|
||
|
|
Usually, .LIB is the extension that is used for library files. |
|
|
|
Example: |
|
|
|
||
|
|
|
|
|
|
LIBX51 CREATE MYFILE.LIB |
|
|
|
* CREATE FASTMATH.LIB |
|
|
|
The TRANSFER command creates a new library file and adds object modules. |
|
|
|
The TRANSFER command must be entered in the following format: |
|
|
|
|
|
|
|
TRANSFER filename (modulename, …) , … TO libfile |
|
|
|
where |
|
|
|
filename |
is the name of an object file or library file. You may specify |
|
|
|
several files separated by a comma. |
|
|
modulename |
is the name of a module in a library file. If you do not want |
|
|
|
to add the entire contents of a library, you may select the |
|
|
|
modules that you want to add. Module names are specified |
|
|
|
immediately following the filename, must be enclosed in |
|
|
|
parentheses, and must be separated by commas. |
|
|
libfile |
is the name of the library file that should be created. The |
LIBx51 library manager will remove a previous version of the library, if this file already exists. The specified object modules are added to the new created library.
Example:
LIB251 TRANSFER FILE1.OBJ, FILE2.OBJ TO MYLIB.LIB
LIBX51 @mycmd.lin
--- content of mycmd.lin: ---
TRANSFER FILE1.OBJ, FILE2.OBJ, FILE3.OBJ TO MYLIB.LIB

Adding or Replacing Object Modules
The ADD command is used to add one or more object modules to an existing library file. The ADD command must be entered in the following format:
ADD filename (modulename, …) , … TO libfile
where |
10 |
|
|
filename |
is the name of an object file or library file. You may specify |
|
several files separated by a comma. |
modulename |
is the name of a module in a library file. If you do not want |
|
to add the entire contents of a library, you may select the |
|
modules that you want to add. Module names are specified |
|
immediately following the filename, must be enclosed in |
|
parentheses, and must be separated by commas. |
libfile |
is the name of an existing library file. The specified object |
|
modules are added to this library. |
Example:
LIB51 ADD MOD1.OBJ, UTIL.LIB(FPMUL, FPDIV) TO NEW.LIB
* ADD FPMOD.OBJ TO NEW.LIB
With the REPLACE command you can update an existing object module in a library file. The REPLACE command will the object module to the library if it does not exist. The format is:
REPLACE filename IN libfile
where |
|
filename |
is the name of an object file you want to update. |
libfile |
is the name of an existing library file. The object module is |
|
replaced in this library. |
Example:
LIBX51 REPLACE MOD1.OBJ IN MYLIB.LIB
* REPLACE FPMOD.OBJ TO FLOAT.LIB

Removing Object Modules
The DELETE command removes object modules from a library file. This command must be entered in the following format:
DELETE libfile (modulename , modulename … )
10 |
where |
is the name of an existing library file. The specified object |
|
libfile |
|
|
|
modules are removed from this library. |
|
modulename |
is the name of a module in the library file that you want to |
|
|
remove. Module names are entered in parentheses and are |
|
|
separated by commas. |
|
Example: |
|
|
|
|
|
LIB51 DELETE NEW.LIB (MODUL1) |
|
|
* DELETE NEW.LIB (FPMULT, FPDIV) |
|
|
Extracting Object Modules |
|
|
The EXTRACT command creates a standard object module for a specified |
|
|
module in a library file. This command must be entered in the following format: |
|
|
|
|
|
EXTRACT libfile (modulename) TO filename |
|
|
where |
|
|
libfile |
is the name of an existing library file. For the specified |
|
|
object module a standard object module will be created. |
|
modulename |
is the name of a module in the library file. Only one module |
|
|
name can be entered in parentheses. |
|
filename |
is the name of the object file that should be created from the |
library module.
Example:
LIBX51 EXTRACT FLOAT.LIB(FPMUL) TO FLOATMUL.OBJ
