A compiler for a subset of the Automated Data Processing Equipment Selection Office (ASPESO) HYPO-COBOL has been implemented on a microcomputer. The implementation provides nucleus level constructs and file options from the ANSI COBOL package along with the PERFORM UNTIL construct from a higher level to give increased structural control. The language was implemented through a compiler and run-time package executing under the CP/M operating system of an 8080 microcomputer-based system. Both the compiler and interpreter can be executed in 20K bytes of main memory. A program consisting of 8.5K bytes of intermediate code can be supported on this size machine. Modification of the compiler and interpreter programs can be accomplished to take advantage of larger machines. The programs that make up the compiler and interpreter package require 50K bytes of disk storage.
