Specifying User Procedure Libraries
NCL procedure libraries are subvolumes that contain NCL procedure source files.
Each individual user (virtual as well as human) and each group of users can have a
private NCL procedure library, known as a user procedure library. User procedure
libraries are not defined in a CONFIG file: you use User ID Management Services to
create a user procedure library for a user or group of users. See Section 4, “Managing
User Access and Privileges,” for specific instructions.
Note User procedure libraries are mentioned here because they are part of the default NCL procedure search
path, discussed later in this section.
Specifying Customized and Distribution Procedure Libraries
There are two procedure libraries that, collectively, are called the “system procedure
library”:
The customized procedure library, which contains:
System-level NCL procedure source files that you write
Customized copies of NCL procedure source files that Tandem distributes
with NonStop NET/MASTER MS
The distribution procedure library, which contains the NCL procedure source
files that Tandem distributes with NonStop NET/MASTER MS (see Appendix A,
“File Reference,” for the names of these NCL procedures)
The NCL procedure source files in the distribution procedure library can be
overwritten by successive installations, new releases, or other software updates; NCL
procedure source files in the customized procedure library are not overwritten.
Note Do not modify the NCL procedure source files in the distribution procedure library. If you want to modify a
distributed NCL procedure, copy the NCL procedure into the customized procedure library, a user
procedure library, or the BSYS virtual user’s user procedure library, and modify the copy. This practice
enables you to retain a working copy of the distributed NCL procedure. See Section 4, “Managing User
Access and Privileges,” for information about configuring the user ID definition record of the BSYS virtual
user.
You must specify the location of the customized and distribution procedure libraries in
the CONFIG file if either of the following two conditions exist:
The NCP program file and a library reside on different volumes.
The name of a library is changed to a name other than its default.
You can specify the location of the customized and distribution procedure libraries by
using the PARAM command operands specified in Table 3-1.
