Run a program or slot.

Syntax #

EXEC program$, slot%
EXEC slot%
EXEC program$

Input	Description
`program$`	The name/path of the program to load.
`slot%`	The program slot to use.

If only slot% is specified, then the contents of the slot will be executed. If only program$ is specified, then the program will be loaded into the currently-running slot, the running program will be replaced, and the new program will start running. If both are specified, then the program will be loaded into the slot and the slot will be executed.

EXEC 2

'load FOO into this slot and run it
EXEC "FOO"

'load FOO into slot 1 and run it
