HI All!

What is the use of cobol scope terminator STRING END-STRING?
And what does the following code mean?

Code:
STRING 'OPEN DATEFILE ERROR, FILE STATUS = '
                                                       DELIMITED BY SIZE
             WS-DATEFILE-FILE-STATUS  DELIMITED BY SIZE
     INTO SPZC-TEXT1
END-STRING

Thanks..................

niharika,

STRING is a COBOL verb, you can use to merge two or more strings to one.

END-STRING, as you already said, is scope terminator for the corresponding STRING verb, which makrs an end of the statement too there.

The code you mentioned will join the two strings resulting into SPZC-TEXT1.

Thus SPZC-TEXT1 would be having 'OPEN DATEFILE ERROR, FILE STATUS = ' and value of WS-DATEFILE-FILE-STATUS in it.

Regards,
Priyesh.

what does "DELIMITED BY SIZE "?


DELIMITED BY SIZE specifies:
All the contents of source-string would be moved to destination-string in the same sequence in which they appear in the statement.
Data movement begins with the leftmost character and continues to the right, character by character.
Data movement ends when the STRING operation has transferred all data in each source-string or reaches the end of dest-string

For a complete information on STRING statement, you can also visit MANUALS...

Priyesh.
