We run IDL 5.2 on our network and I have 5.4 on my laptop. While reading in
tab delimited data into an array, IDL 5.2 skips whole lines of data, but 5.4
does not. I find this a bit alarming. Am I doing something weird?
Cheers, Christophe Fraser

How did you read, tell us a bit more!
Did you something like:
header=make_array(/string,1)
values=make_array(/float,5,10)
openr,lun,file,/get_lun
readf,lun,header
readf,lun,values
free_lun,/lun
I have never seen such a problem as you described.

Well if you're interested, here's the code that reads in the data:
dataread=0
if dataread eq 0 then begin
CD, 'U:\VAIO2\C Code\residual'
Nloops = 200L
NR0Steps = 200L+1
arraydet = dblarr(3,NR0Steps)
arraystoc = dblarr(3,(NR0Steps)*Nloops)
OpenR, 1, 'residual1.txt'
ReadF, 1, arraydet
ReadF, 1, arraystoc
Close, 1
endif
Cheers, Christophe.

What kind of line end character did you wrote.
is it LF or CR LF.
I learned that's IDL on windows need CR LF. And I am sure
if you wrote the data by IDL you will be able to read it
correctly. If you have a HEX Editor you will see the differences.
