CA-C Runtime

CA-C Runtime is a run-time facility with reentrant capabilities. Its modular architecture insulates CA-C Runtime programs from system and version dependencies. There is little, if any, system-dependent code linked with the user program. This allows for smaller user programs and easier maintenance. CA-C Runtime uses a memory manager to handle dynamic allocation requests for small pieces of storage. This enables fewer calls to be made on the operating system, resulting in faster allocation and deallocation. CA-C Runtime features include:

• Calling functions written on other languages, such as Assembler or COBOL
• Runtime kernels for each host environment
• Device drivers for each environment
• Single data structure for entry points
