Recently, a couple of folks have asked for the syseval or address for
the builtin EDIT/VISIT routine. I find myself now interested in that
also, as I've started writing a simple-minded text manager. It would
be a lot smaller and easier to just shove a string in to be edited than
to do it manually, so if anyone knows how to programatically invoke
EDIT or VISIT, I'd really like to know.
Also, I needed to convert a string into a global name object, and after
a little experimentation, I came upon the following code to do that.
It seems there ought to be an easier way -- does anyone know of an
easier method of doing this type of conversion?
"string" --> 'string' (when a variable exists called string)
<< "'" SWAP + "'" + OBJ-> >>
(Normally one could just do an OBJ->, but if a variable in
the current directory exists called 'string', then the double
quoted version is resolved down to the contents of the variable.
I don't want that; I want just the global name object.)
Thanks much!
bruce

Bruce,
Yes, there is a SYSEVAL to convert Strings to Global Names. I don't have
my list with me, though. I'll post it later, if know one beats me to it
:-)

Bruce & Derek: #5B15 SYSEVAL converts a string to a global name. This info is from your address comment file, Derek. [jkh]

"'" SWAP + OBJ\-> is all that's required, since the parser is intelligent and will assume the final "'". An easier way? What could be easier than that? > > Thanks much! > > bruce -- John W.
