但是,如果不存在符合优化条件的 COBOL CSECT,那么不会向输出模块写入任何内容。 当指定 REPLACE=N 时,如果已存在输出模块,那么将绕过输入模块的优化或扫描;并且不会向输出模块写入任何内容。 您可以使用 REPLACE=N 来绕过对已优化模块的优化。例如,如果在优化了二进制文件后向原始数据集添加了新成员并且只想优化新成
COBOL is one of oldest programming languages. Although it is the most widely used programming language, it''s architecture is admittedly antiquated and is very poorly thought of, especially in academia. With so many substantial improvements in programming language technology over the past thirty ...
However, if there are no eligible COBOL CSECTs present that can be optimized, nothing is written to the output module. When REPLACE=N is specified, optimization or scanning of the input module is bypassed if the output module already exists; nothing is written to the output module. ...

This kind of change has happened before: in the early days of computing, programmers “wrote” programs by plugging in wires, then by toggling in binary numbers, then by writing assembly language code, and finally (in the late 1950s) using early programming languages like COBOL (1959) and ...
getting off [COBOL means] that it's become a lot easier, rather than a lot harder [to hire people], because a lot of [organisations] are getting rid of that technology stack, and it's easier for us to secure resources there. It's easier now than it ever was in the past," he ...
