IF Clause on the END LOOP Statement (MATRIX-END MATRIX command)

When an IF clause is present on an END LOOP statement, the logical expression is evaluated after each iteration of the loop structure. If it is true, the loop terminates and control passes to the statement following the END LOOP statement.

• The IF clause is optional.
• As in the LOOP statement, the logical expression of the IF clause is evaluated as scalar, with positive values being treated as true and 0 or negative values, as false.
