The use of computer language compilers in legacy code migration
K.C. Chisolm, J.C. Lisonbee · 1999
This paper begins with the premise that computer hardware will be replaced, and this will cause a significant impact on the associated legacy software. The paper will present the advantages of utilizing compiler design techniques in solution of legacy code migration. The primary advantages include lower costs to support a large body of test programs, decreased costs of future system upgrades, and continued support of Test Program Sets (TPS) code in the legacy language. A brief review of compiler design theory will also be presented. This review will concentrate on unique aspects involved in use of ATLAS combined with manufacturers native languages.
