Sets the file pointer of the read stream file so that the next READLIST, etc., begins reading at the
charpos-th character in the file, counting from 0.
SETREADPOS 0 starts reading from the beginning of the file.)
This is meaningless if the read stream is .
OPENWRITE "dummy.fil SETWRITE "dummy.fil PRINT "Hello PRINT [Good Bye] SETWRITE  CLOSE "dummy.fil OPENREAD "dummy.fil SETREAD "dummy.fil SHOW READLIST[Hello]
SETREADPOS 0 SHOW READLIST[Hello]
SETREAD  CLOSE "dummy.fil
