The workaround for putting selfmodifing programs into a library is to put
the following shell around them:

  \<< { qed } OBJ\-> DROP   @ here 'qed' is the command that modifies itself
      #7E99h SYSEVAL DROP   @ ROMPTR@ - recall pointer to library command
      NEWOB EVAL            @ copy ob into TEMPOB, execute it from there
  \>>

[Of course, replace "qed" above with whatever library command you
wish.  It'll work with any self-modifying program as long as there's
enough free memory for NEWOB to make a second copy of it.  If this
workaround fails at NEWOB with an "Insufficient Memory" error, then
you're out of luck.  -jkh-]
