Legacy Tools (RPG, COBOL)

Keller Schroeder’s experience with RPG and COBOL is deep and wide. These tools have existed for a long time, and we have been developing, enhancing, and integrating solutions in these environments for many years. Considering the millions of lines of legacy code in production today, it will be many years before they are replaced.

Unlike other firms that have “jumped ship” for new technology waves, we know these production solutions are often still performing effectively with no business case for replacement. We have been there for our clients with these technologies in the past, and we will continue to be there for them for years to come.

Our IBM midrange expertise includes: System i, iSeries, AS/400, S/38, S/36, and S/34. We support solutions using earlier generation tools such as RPG II, OCL, and RPG III, but we have made use of other tools and techniques as they have become available such as RPG/IV, embedded SQL, free-form RPG and stored procedures.

Our IBM Mainframe experience includes:

  • MVS and VM using TSO and ISPF
  • DOS/VSE using ICCF and Power
  • IMS using DL/I and DB2 using SQL
