Symbol Goto

→ — Branch to a line in a function — Keystroke ALT+] — Character 8594 or 0x2192

Alternate Names

This symbol is also known as right arrow or APL text symbol {rightarrow}.

Usage

The goto symbol may be used as a conditional branch (branch based on a comparison) or an unconditional branch, or it may be used to exit a function. It is most often used in a function to transfer control

Unconditional branch

The goto symbol is followed on the right either by the line number or a label. Execution continues in the function at that line (unless the line specified is 0, in which case the function exits.)

Exit Function

The goto symbol may be used to exit a function and return to the calling function (or return to the session manager if the function was called by the user typing its name) by using 0 as the line number to goto.
