MCI Network Services -- Network Services Billing System

MCI (now Verizon) used the Promula Fortran translation software to rehost three legacy applications:

 

  • Network Services Billing

  • Network Order Entry System

  • Phone Access Database

 

from a legacy source platform:

  • DEC 36-bit mainframe hardware

  • TOPS/ICS operating system

  • XF4 FORTRAN/KCC C code base

  • System1022 database

 

to a contemporary target platform:

  • IBM RS6000 hardware

  • AIX operating system

  • ANSI C code base

  • ORACLE database

 

To achieve the objectives of this project, Promula developed a number of migration tools:

  • PXF4, an XF4 FORTRAN-to-C Translator

  • PICS, an emulation of the ICS command line interpreter for UNIX

  • PL1022, an emulation of the System 1022 database language (and its FORTRAN and C call interfaces) for UNIX and ORACLE SQL

  • XF4LIB, a library of XF4 FORTRAN functions for UNIX

  • AIXLIB, a library of DEC TOPS operating system functions for AIX

  • KCCTRANS, a KCC-to-ANSI C translation tool

  • FILGE, a DEC text editor for UNIX
