Your problem is that tab is a character, i.e.:

>> print type? tab
char

The parse function is looking for a string, so just give it the tab as a
string value:

page: read/lines %textfile.txt
   foreach line page [
  line: parse/all line "^-"
   ]

and it will work like the true champ that REBOL is.

Enjoy.

>> probe tab
#"^-"
== #"^-" 

page: read/lines %textfile.txt
foreach line page [
line: parse/all line "^-"
]
