Nope. But I can shift the problem a little.
It may or may not make sense for your script but if you give the action a
name then you don't need the parens:
>> my-action: [(print "i'm here!")]
== [(print "i'm here!")]
>> parse [ x ] compose [(to-word "w

Now i've started to read the dbms code. The first notes:

2) I do not like to use a dir for a db. Neither to use a dir name for a db
name. My preference

Hi paolo and andrew,
Thanks to both of you. However I do not understand how it works. Especially
what find/last is doing.
For example:

find/last file "."
== %.r
So it returns the end of the file (or the end of the string in my previous
post). However you are bo
