Basics

1 to 6 : Sequence number area | 7 = indicator area | * d
8 to 11 = A area | division 12 to 72 = B area | statement, setences, etc 73 to 80 = identificator area | ignored by compiler

division -> sections -> paragraphs -> sentences -> statements

division = Author, enviroment, data division (memory, storage), precedure

paragraphs = like funcions, can call somewhere

IF ITEM = "B" ADD 2 TO TOTAL END-IF

sentence = ADD 2 TO TOTAL. statements = ADD, TO, .

DOT = ending

Variables

Picture = length of variable PIC 9 = single numeric value, length one 9 means numeric PIC 9(4) = length numeric of 4. 9999 PIC A = single character alphabethic PIC X(8) = letters and numbers

PIC 9(4)V99 = MAX 9999,99 PIC $9,999V99 =

PIC x(32) VALUE SPACES = String(" " * 32)

Data division

keywords

MOVE = moves data into a variable

SOME-VARIABLE PIC X(32).
SOME-NUMBER PIC 9(1)
MOVE "Some String" TO SOME-VARIABLE.
COMPUTE RESULT = SOME-NUMBER * SOME-NUMBER.
