What is the .RNO File Extension?

.RNO File Extension Description:

The RNO file extension is identified with the old source files of RUNOFF, a text formatting application found on old minicomputers and mainframes. It handles most of the directives in RUNOFF and is similar in concept to other utilities such as Lex, LaTex, or Tex. This utility includes a few additional features such as the columnar output which can be simply be downloaded to any directory where you want it to reside.

RUNOFF, assumed to have come from the phrase "I'll run off a copy", is written for the CTSS operating system. This operating system is actually consists of a pair of programs, namely TYPSET and RUNOFF. TYPESET is the document editor whereas RUNOFF is the output processor which provides support for pagination and headers.

When sent across a network through VMS MAIL or colored-book POST, RUNOFF documents suffer distortions in which the lines that were supposed to be printed on top of each other are printed below each other and as a result, these documents that contain underlined or bold-faced text cannot be correctly reproduced.

For this reason, RUNOFF documents are sent in the form of raw files with the .rno file extension leaving the processing to the recipient. This solution, however, only works for RUNOFF since the recipient has no access to the document's original special processing aids, therefore, it can have problems transmitting the document into an acceptable form.

The files with the .rno file extension can be reformatted before mailing them so that they cannot be corrupted by MAIL and as such, can also be processed by VMS editors. These files can be restored to their original files with the .rno file extension so they can be used with POST, which does not transmit MAIL-reformatted documents.

If the file with the .rno file extension is output onto a record device such as a printer or terminal, the carriage control information contained in the text records is affected but by replicating the records on the device, the text comes out in its preferred form. The carriage control provided before or after each record contains only text but by applying such control in a number of ways, the file's record attribute can be PRINT or IMPLIED.
