2.6.1 Calling, libraries and files

The MODULEF library [Bernadou et al. 1988] is organized into several sets of programs or (sub-)libraries as indicated in chapter 1. In the same way, the programs concerning three-dimensional meshes are found in NOP3, etc.

There are two ways of calling module APNOP3:

1. via preprocessor APN3XX, or
2. directly.

In the first case, we must perform a link between libraries CONV, CONW, NOP3, NOPO, UTSD, UTIL and UTIF (general non-portable utilities) and program APN3XX .

In the second case, the libraries required are the same as above, except for CONV and CONW, which are now redundant.

A calling program, in FORTRAN 77, must be written in the following manner:

• COMMON M(LM)
  Declaration of the super-array M, of LM words
• EXTERNAL XYZ23,XYZ33, F2D3D
  Declaration of the "functions"
• CALL INITI(M,LM,IMPRE,NNN)
  Initialization for all the MODULEF jobs
• CALL APNOP3(M,M,XYZ23,XYZ33,F2D3D)
  Call the module
• STOP
• END

The only arguments of this module are the super-array, M, and the formal name of the three possible functions. The data is contained in a command file in the form of keywords and associated values.

The list of keywords, classed according to their logical level, are given below. For each value, the corresponding type expected is indicated ((I): Integer, (R): Real, (A): Character, etc.).
