I don't think OLD is allowed in a program, only from the command line.

The virtually identical method I've seen in the past though, as already
mentioned somewhere here, is to program a function key with that
command line and then insert it into the keyboard buffer, e.g.

9000 *KEY 0 F.I%=0TO TOP-PAGE STEP4:I%!&E00=!(I%+PAGE):N.|MPAGE=&E00|MO.
|MRUN|F|M
9010 VDU 21
9020 *FX 15
9030 *FX 138,0,128
9040 END

VDU 21 disables output so that we don't see the command entered on the
screen.  Notice this is re-enabled by inserting a Ctrl-F (|F) into the
buffer within the *KEY 0 definition.

*FX 15 clears the keyboard buffer before inserting function key 0.
