On Goto

Home › Control Flow Statements › On...Goto

On...Goto

Jumps to a label based on an expression.

Syntax

On expression Goto label1[, ...]

Description

Branches to different labels depending on the value of expression. An expression value of 1 will branch to the first label, a value of 2 to the second, etc. If the value of expression is zero (0) or greater than the number of items in the list, execution continues on the next statement following the On...Goto.

It is recommended that the structured Select Case conditional statement be used instead of On...Goto.

Remarks

Differences from QB

• FreeBASIC does not generate a run-time error if expression is negative or greater than 255.
