1705	 A Set of Basic Input-Output Procedures Algorithm	 By means of the primitives in symbol outsymbol and length as requested by this journal s Algorithms Policy Comm. ACM Nov. a basic set of input-output procedures is defined aiming at quality and flexibility. Outreal for instance is written as a derived procedure it outputs using the fixed point or the floating point representation and rounds properly. Variants can easily be written because of the explicit call of the procedures decompose integer and decompose real. The highly recommended practice of echoing input is made easy with one subset of derived procedures ioi ior iob ioa . The documentation of output in the form of equivalent ALGOL statements is also provided when use is made of the subset oti otr otb ota. The Berkeley style of providing information on the form of output using prior calls of procedures such as real format is defined. A use of the parameter outchannel to provide information for simultaneous output to several channels is suggested. Interrelationship between the declared procedures is furnished in tabular form. input output transput input output procedures input echo quality output decompose integer decompose real style Berkeley style procedures relationship output documentation equivalent ALGOL statements ALGOL ALGOL integer format real format out integer read real input output Boolean input output array fixed point representation floating point representation output channel interpretation
