What is SET TO TRUE all about, anyway?

In COBOL II the 88 levels can be set rather than moving their associated values to the related data item. (Web note: This change is not one of COBOL II's better specifications.)

RE: What is SET TO TRUE all about, anyway?

The set to true is done for 88 level variables to set that flag

For eg: 05 ws-change-flag pic x(1).

88 ws-chg value 'Y'

88 ws-no-chg value 'N'

when set ws-chg to true is done then ws-change-flag contains value 'Y' .It is same as move 'Y' to ws-change-flag

If the statement is set ws-no-chg to true then ws-change-flag contains value 'N'.It is same is move 'N' to ws-change-flag

At one point of time only one flag can be set.

no it is not like that.

if in a level no. 88 if there is more than one one condition then if i want to true only first condition then we use SET TO TRUE condition.for example-

77 ws-status pic x(8).

88 married-value "1" "2" "3".

Then if i want to true only first condition i.e (1) then in a PROCEDURE DIVISION you just give a statement-

married-value set to true.

RE: What is SET TO TRUE all about, anyway?

no, its not like that..according to me first answer is right..!

e.g. 05 ACCOUNT-TYPE         PIC X(01) VALUE 'N'.
             88 PREPAID-ACCT                     VALUE 'Y'.
             88 POSTPAID-ACCT                 VALUE 'Y'.

Use this in:-

SET POSTPAID-ACCT TO TRUE

This will set the post paid value to Y.

SET PREPAID-ACCT TO TRUE - THIS WILL SET PREPAID=Y

RE: What is SET TO TRUE all about, anyway?

Last answer is correct and below example also.
e.g. 05 ACCOUNT-TYPE         PIC X(01) VALUE 'N'.
             88 PREPAID-ACCT                     VALUE 'Y'.
             88 POSTPAID-ACCT                 VALUE 'Y'.

Use this in:-

SET POSTPAID-ACCT TO TRUE

This will set the post paid value to Y.

SET PREPAID-ACCT TO TRUE - THIS WILL SET PREPAID=Y
