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
