C.l5.l. Appending Function Modules
This call has the fOllowing format:
$MOD comfile rsxl rsx2 ••• rsxl5
The first parameter "comfile" denotes the 11 .COM 11 file to be extended by
function modules. It is followed by a list of the RSX files which
contain the modules to be appended. A maximum of 15 modules can be
specified for a ".COM" file. The modules are loaded in the same sequence
as specified in the coffimand line. This has the side-effect that of two
modules which intercept the same system call, the one most recently
loaded will be active.
If the ".COM 11 file is already extended by modules, the modules specified
new are appended after all yet existing modules. If a module occurring
in the list should be present in the ".COM" file, it will be replaced by
the new one.
An example: You have a file named
11
PROG.COM". This file contains the
modules
11
MOD1",
11
MOD2
11
and "MOD3" (maybe, besides the main program). Now
you enter the command
$MOD PROG MODl MOD4
This causes the module MODl in the PROG.COM file to be replaced by the
new module MODl. The module MOD4 is appended at the end of the list.
When you execute the program, first the module MOD4 intercepts EOS
calls, then MOD3, MOD2 and finally, MODl.
C.l5.2. Removing Function Modules
To remove all function modules from a ".COM 11 file (thus causing a normal
".COM" file being generated), you would simply omit the module specific-
ations from the command line:
$MOD progname
By that means, all modules are removed from the file "progname.COM
