Summary
Programs are frequently split into sections. For instance declarations are specified separately from instructions, comment headings document each procedure, and procedures are specified before the program. The sections may specify program overlays or they may divide a program into single-entrance/exit modules. Program sections are heavily used in COBOL and RPG where programs are split into an environment division, a data division, input and output divisions, and calculation divisions. (cbb 5/80)
