The function of the DISPLAY statement is just opposite to that of the ACCEPT statement. It is used to display the low-volume results on the operator's console or various other hardware devices. The common format of the DISPLAY statement is
If the UPON option is absent, the values of the identifier-1/literal-1, identifier-2/literal-

The mnemonic name, as in the situation of the ACCEPT verb, must be defined in the SPECIAL-NAMES paragraph. Whenever more than one operand is specified, then the values of the operands are displayed in the series they are specified. There will be no gap between these values. The operands should be of the usage DISPLAY. The literals may be any of the literal or figurative constant apart from the ALL literal. If the figurative constant is specified, then only one occurrence of the constant is displayed.
Illustration:

DISPLAY " SUM IS", THE-SUM
And assume that the picture and present value of THE-SUM are 9(3) and 15 respectively. Upon execution of the statement, then the result will be displayed on the console
SUM IS 015
