Set line length was employed by some early mainframe running techniques. In this type of procedure, an implicit conclude-of-line was assumed each individual 72 or 80 characters, as an example. No newline character was saved. If a file was imported from the outside environment, strains shorter than the road duration had to be padded with Areas, while lines lengthier than the line duration had this content to be truncated. This mimicked using punched cards, on which Just about every line was saved on a individual card, commonly with eighty columns on Each individual card, often with sequence numbers in columns 73–80.
