Principles of Compilers: A New Approach to Compilers Including the Algebraic Method
"Principles of Compilers: a brand new method of Compilers together with the Algebraic approach" introduces the tips of the compilation from the usual intelligence of humans by way of evaluating similarities and adjustments among the compilations of normal languages and programming languages. The notation is created to record the resource language, objective languages, and compiler language, vividly illustrating the multilevel technique of the compilation within the approach.

SPECIAL-NAMES. CURRENCY SIGN IS 11£11. INPUT-OUTPUT SECTION. SELECT output-file ASSIGN TO PRINTER. 6 Chapter Summary I (a) Computing is a process that can be summarised as • • • data is input to a program the program processes the data results are output by the program. (b) The first COBOL Standard was defined in America in 1959, with revisions in 1968, 1974 and 1985. All new Standards are upwards compatible with old Standards, though some obsolete items may be removed. Standard COBOL is portable across platforms.
For example, given the data definitions 01 01 price new-price PIC 9999V99 USAGE BINARY. PIC 9999V99. then the statement MOVE price TO new-price will convert the value automatically from binary format to the (default) display format. 1 2 •8 The INITIALIZE Statement I In the Section above, MOVE was used to set 00-3 to a value of zero. g. MOVE SPACE TO your-name. 4: 01 input-details. 03 ref -number 03 description 03 price PIC 9(6). PIC X(30). PIC 999V99. If it was required to set numeric fields to zero and non-numeric fields to spaces at some point in the program, this could be achieved by a series of MOVEs: MOVE SPACES TO description, ••• MOVE ZEROES TO ref-number, price, Alternatively , the INITIALIZE verb could be used: INITIALIZE ref-number, description, price, Data and Procedure Division Fundamentals 37 However, as the fields are all part of the same record data structure, a much simpler method is: INITIALIZE input-details as the INITIALIZE verb will put zeros in all numeric fields and spaces in all nonnumeric fields at all lower levels.
VALUE "T". The level 88 entry is known as a condition name. It does not put an initial value in the data item, but specifies a condition that is true when the data item value changes to the value on the level 88 entry. The conditions end-of-file-flag "T" and end-of-file are equivalent. At the start of the program, the value in end-of-file-flag is "F", so the condition endof-file is false, and the condition NOT end-of-file is true. Standard COBOL does not have a Boolean data type, but use of level 88's can simulate such a data type.
