Different Forms of an Interface Module - Compilation

An Interface Module can exist in two forms. When an application program is being developed, the information making up the Interface Module is normally put into an ordinary text file, where it can be easily inspected and edited. The file should have the same name as the program, but with a file extension of .ifl.

When the system interface for a program has become relatively stable, the Interface Module can be saved in compiled form - this leads to a more efficient running of the system. The compiled form has the same name as the source file, but a file extension of .ifc.

Strictly speaking, the source file is the Interface File although that term is often used to mean either source or compiled forms of the Interface Module.

The program compifl is provided to compile an Interface File. Perform the usual startup procedure for ADAM program development then type:

compifl filename
in response to the command language prompt. filename may optionally include the .ifl extension. filename.ifl will be compiled into filename.ifc.
