Subj: Everlasting Lambda Variables
Date: 11 Jan 1993

--> S/SX/G/GX

While programming in sys-rpl I found something unusual.

Usually when a program ends, all the lambda (aka local or temporary)
variables are cleared: they no longer exist, even when the program
doesn't do it explicitly (by the ABND command).

Here is a little program that allows you to bind something to a lambda
variable that still exists even after a KILL or a CONT.

It takes two arguments: any object from level two and a global name
from level 1.

Execute it and then press ON when prompted to do so; the program will
be aborted but a lambda variable that contains the object in level
two, named the same as the global name you entered, will be created
and will remain in existence until you execute an ABND command (or a
warmstart).
 
Unusual isn't it ?
