Syntax[edit]
UNTIL condition
Description[edit]
UNTIL can be used in two ways. The first, as part of the REPEAT...UNTIL loop, causes a sequence of lines to be repeated until a condition becomes true. The second, as part of the WAIT...UNTIL statement, halts all processing until a condition becomes true.
Examples[edit]
UNTIL INPUT 0 IS ON AND INPUT 1 IS ON
