rebol - file stop read when line reached -

-

i have code below begin read rest of file after have found line containing string "start" 

   foreach line clines [       if find [%start] line [       print line      ]    ]

i can't figure out documentation.. what's going on here? seems logical me.

you have read file before can search in content of file.

maybe looking like

clines: read/lines %myfile found: false foreach line clines [     if [         found          found:  find line "start"     ]  [         print line     ] ]

an other way be

cfile: read %myfile print [     cfile: find cfile "start"     find/tail cfile lf ]
