Hi,

Please confirm my understanding on escape Bottom.
Escape Bottom executes the next line following the loop.

If i code an escape bottom between IF- ENDIF , then the statement after ENDIF would be executed.

So, in below ex MOVE *TIMN TO #TIME and below wud be excecuted .Please let me know if i understand it correctly.

Also how wud Escape Top work here if coded instead of Escape Bottom.

RD01.
READ (1) TABLE WITH KEY = #KEY

IF FLAG EQ #FLAG AND
TABLE EQ #TABLE AND
MOVE *ISN TO #ISN
ESCAPE BOTTOM
END-IF
*
MOVE *TIMN TO #TIME

IF #ISN=0
STORE A RECORD
ET

END-READ

Thankyou all for your help.

ESCAPE (TOP, BOTTOM & ROUTINE) can be coded only within a loop or routine. They are not valid within IF.

Hi

the Escape bottom comes out of the IF-ENDIF(if the condition is true) and it wont execute the next statement

RD01.
READ (1) TABLE WITH KEY = #KEY

IF FLAG EQ #FLAG AND
TABLE EQ #TABLE AND
MOVE *ISN TO #ISN
ESCAPE BOTTOM
END-IF
*
MOVE *TIMN TO #TIME

IF #ISN=0
STORE A RECORD
ET

END-READ

in this code Escape bottom comes out of the Read and executes the next statement after the read

in the below example if u give escape top
RD01.
READ (1) TABLE WITH KEY = #KEY

IF FLAG EQ #FLAG AND
TABLE EQ #TABLE AND
MOVE *ISN TO #ISN
ESCAPE TOP
END-IF
*
MOVE *TIMN TO #TIME

IF #ISN=0
STORE A RECORD
ET

END-READ

it comes out of IF (if the condition is true) and again goes back to the read statement and doesn't go to the next statement(move statement)

and comes out of the read as u have given READ(1). if u have as READ it reads another record.

Hope u got it
