LMS processes PLAM libraries. PLAM libraries are PAM files in BS2000 that are processed with the library access method PLAM (Program Library Access Method).
A PLAM library contains members and a table of contents or directory of these stored members. PLAM libraries are used for the storage of source programs, macros, object modules, phases (load modules), lists, procedures, text etc. They are characterized by the following:
all member types can be processed in a single library with standardized statements,
members with identical names may exist which are distinguished only by their type or version designation,
the library can be accessed by several users simultaneously, even in write mode,
for most data elements (=members) produced during a software development process, uniform data storage exists with standardized access functions and
the utility routines and compilers can access this stored data and process the individual members directly.
Program libraries are also referred to simply as “libraries” in the following:
