Hi, Andrew,
Thanks for your reply. I don't think it is the problem of a simple while loop. I
attached my script and input file in this msg:
blk: read/lines %test.dat
while [not empty? blk]
[
d1: second (to-block first blk)
d1: parse d1 "-"
d1: to-date d1/1
print d1
blk: next blk
print blk
either not empty? blk [print "not empty"][print "empty"]
]
test.dat:
21-Feb-2000 { 2000/02/01-00:20 - 2000/02/08-21:48 } 76 29
20-Feb-2000 { 2000/02/02-00:20 - 2000/02/08-21:48 } 76 29
19-Feb-2000 { 2000/02/03-00:20 - 2000/02/08-21:48 } 76 29
This test.dat file is generated by machine. The weird thing is if I open the
file and clear its tail, the script worked fine. But if I added an empty newline
at the end of file, it won't work.
** Script Error: Out of range or past end.
** Where: d1: second (to-block first blk)
When rebol execute
either not empty? blk [print "not empty"][print "empty"]
it always prints 'not empty' even the content of blk printed is blank.
I'm so frustrated about this. Can u help me out?
Thanks a million.
Tiana
