PREFIX file

PREFIX is a file of which a copy is placed in \phoenics\d_allpro at installation time.

However, if the user places a file with the same name in his or her working directory, that file will be used by the PHOENICS modules instead of the one in d_allpro.

PREFIX is read by the SATELLITE, EARTH, PHOTON, AUTOPLOT, and PINTO programs for file-descriptor data needed during program execution. The parameters which it sets are:

  1. PHIDA=T or F. Use direct-access or sequential PHI file.
  2. XYZDA=T or F. Use direct-access or sequential XYZ file.
  3. IPRE=T or F. Use default filenames as defined at installation time, or allow interactive input of data file names.
  4. LPHI=T or F. When IPRE=T, specifies whether a PHI file is to be used.
  5. LXYZ=T or F. When IPRE=T, specifies whether an XYZ file is to be used.
  6. DF09US=T or F. When set true, specifies that input to PHOTON is a DF09 file from PHOENICS version 1.3 or earlier.
