CLEARSELECT

Use the CLEARSELECT statement to clear active select lists.

COMMAND SYNTAX

    CLEARSELECT { ListName | ListNumber }

    B = "night" : @AM : "day"
    SELECT A TO 3
    SELECT B TO blist
    adone = 0 ; bdone = 0
    //
    LOOP
     READNEXT Ael FROM 3 ELSE adone = 1
       READNEXT Bel FROM blist ELSE bdone = 1
    UNTIL adone AND bdone DO
       CRT Ael, Bel
       CLEARSELECT 3
