mapp Services V5.16

Statements can be executed repeatedly with the REPEAT statement.

Syntax

REPEAT
    <statement_list>
UNTIL
    <expression>
END_REPEAT;

The statements in <statement_list> are repeatedly executed until expression <expression> returns the value FALSE. Terminating condition <expression> is checked only after the statements in <statement_list> have been executed. This means that the loop runs at least once, regardless of the terminating condition.

If expression <expression> never has the value TRUE, then the statements will iterate infinitely, causing a runtime error.

Example

REPEAT
    Var1 := Var1 - 1;
    Var2 := Var2 * 2;
UNTIL
    Var1 = 0
END_REPEAT;
