IS NUMERIC is used to check if the data is numeric or not.
IS NUMERIC clause IN COBOL EXAMPLE
01 WS-TEXT PIC X(05).
MOVE '15623' TO WS-TEXT.
IF WS-TEXT IS NUMERIC DISPLAY 'NUMBER'
ELSE
DISPLAY 'TEXTUAL CHARACTERS’
END-IF.
Output:
NUMBER
MOVE 'HE123' TO WS-TEXT
IF WS-TEXT IS NUMERIC DISPLAY 'NUMBER'
ELSE
DISPLAY 'TEXTUAL CHARACTERS’
END-IF.
Output:
TEXTUAL CHARACTERS

ReplyDeleteNo es numerico.
DeleteGood info .
ReplyDeleteFor real time scenario based Mainframe interview questions with good explanation,please refer

What will happen if the value in WS-TEXT is shorter than the length of the variable ? The result of IS NUMERIC is TRUE or FALSE ?
ReplyDeleteFor example :
01 WS-TEXT PIC X(10).
MOVE '1562 ' TO WS-TEXT.
In cobol, moves are controlled by the size and type of the receiving field. Therefore, the resulting value will be "1562 ": not numeric.
