MEMORY

Main storage. (See STORAGE.)

MODE

A system of data representation used within the storage section of a data processing system.

NUMERIC

  1. With respect to data, having a numeric value. 2. With respect to literals, consisting wholly of numerals and their included decimal points, plus and minus signs, and floating point symbols, if any.

OBJECT PROGRAM

A program in machine language resulting from the translation of a source program by a processor.

OBJECT TIME

The time at which an object program is executed.

OPEN SUBROUTINE

In the Commercial Translator system, a section of procedure which is executed by a means other than the DO command. Also called an "in-line" subroutine. (See also CLOSED SUBROUTINE.)

OPERAND

In the Commercial Translator language, the "object" of a verb—i.e., the data or equipment governed, or operated on, by a verb.

OPERATOR

In the Commercial Translator language, a word or symbol, other than a verb, which directs the data processing system to take some action. E.g., the arithmetic operator + instructs the system to perform an addition, and the conditional operator IF directs it to test a conditional expression.

PARAMETER

In the Commercial Translator system, a value used in a procedure to obtain a result; specifically, an item of data named in the USING clause of a BEGIN SECTION command. (See the discussion of functions in Chapter 2 of this manual, and the BEGIN SECTION command in Chapter 3.)

PARAMETER-NAME

A name assigned to a parameter by the programmer. (See PARAMETER.)

PROCEDURE

In the Commercial Translator system, a sequence of one or more instructions used to perform some operation. A routine or subroutine.

PROCEDURE DESCRIPTION

That portion of a Commercial Translator program which consists of instructions directing the data processing system to take specified actions. The procedure description is one of the three main divisions of a Commercial Translator program, the others being the data description and the environment description.

PROCEDURE-NAME

A name assigned by the programmer to a procedure for use in a Commercial Translator program, in accordance with the rules given in Chapter 2 of this manual.

PROCESS TIME

The time at which a source program is translated into an object program.

PROCESSOR

A specialized program used to translate a source program into an object program.

PROCESSOR VERBS

Verbs which give instructions to the processor to be acted upon at the time the source program is being translated into the object program. Such verbs do not act at object time.

PROGRAM

A complete sequence of instructions directing a data processing system to perform an operation. The term implies an extended sequence incorporating all of the detailed steps and subroutines required to complete a job. (See also OBJECT PROGRAM and SOURCE PROGRAM.)
