a reference towards an element in an array is done by means of a subscript. The first occurrence of an element in an array has subscript 0.

arrays are used to read in DB2 tables

a program must always begin with a PROCEDURE statement and end with an END statement

PL/I instructions can be coded between positions 1 and 72

you have to declare each variable that you are going to use

a program can be composed out of different procedures

PIC ‘(5)9’

PIC ‘S(3)9V.99’

PIC ‘S999.99’

PIC ‘999V99’

REPEAT 5 TIMES; instruction; END;

DO J=1 TO 5; instruction; END;

COUNTER = 1; DO WHILE COUNTER < 5; COUNTER = COUNTER + 1; instruction; END;

REPEAT VARYING COUNTER FROM 1 BY 1 UNTIL COUNTER = 5; instruction; END;
