Monoliths

For efficiency, a group of related programs can all be linked into a single executable file called a monolith (see SG/4). If the monolith is to be run from ICL, the individual Interface Files must be concatenated into a single file for the whole monolith and the monolithic Interface File must have the same filename as the executable file. The structure of a monolithic Interface File is as follows:

MONOLITH monname
   INTERFACE programname_1
      .
      .
   ENDINTERFACE
   INTERFACE programname_2
      .
      .
   ENDINTERFACE
ENDMONOLITH

where programname_1, programname_2, etc. are the names of the individual programs. They must comply with the rules for action names (see Appendix ).

When monoliths are run directly from a Unix shell, the individual program Interface Modules are used.
