What's the difference between COMEFROM and attaching a hander to an event?
- Someone 7y agoCOMEFROM doesn’t execute whatever is at the place where the jump to the COMEFROM happens, and doesn’t provide a way to return there. (Aside: for a variation on COMEFROM, see Cobol’s ALTER (https://en.wikipedia.org/wiki/COBOL#Self-modifying_code https://en.wikipedia.org/wiki/COBOL#Self-modifying_code).)
