GENRE

Narrow Plasmon Resonances in Hybrid SystemsA COBOL program would often be written down on a coding sheet (see attached example); it is necessary when doing this — and later when keying the program in to the machine — to follow certain rules:

Foment

Daniel Denninger,Maik Berger,Yordan KyosevEach item of data that your program is going to use must be described and named — thus setting aside data storage space in Central Memory; this is done in one of the sections of the Data Division (e.g. the Working-Storage Section).
