Re: How to put comment on HPUserEdit

At the expense of more memory use, however,
plus a slight run-time overhead,
one can sprinkle into one's programs:

"My comments about what I'm doing" DROP

One can also attach "tags" to some objects,
since commands which do not attach special meaning
to "tagged" arguments generally automatically
strip tags during argument processing; e.g.
the following executes the "system word" named "TRUE"
(although SYSEVAL uses only the address part,
and takes no interest in what you think its name is :)

:TRUE: #3A81h SYSEVAL

A "SYSEVAL translator" package (created for migrating
UserRPL programs containing SYSEVAL from HP48 to HP49)
took advantage of this to attach the correct name
to every argument of SYSEVAL on the HP48,
and then to use those names to look up and replace
the (generally different) address within the program
itself, after transferring the program to an HP49
(this was essentially a program pre-editor,
not a run-time operation).

I also wasted memory by posting some of my programs
with the tags included, just as documentation,
even though I'd mention that they weren't necessary :)
