What i do in fact is:
readf,11,format='(9e14.6,A1)', a,b,c,d,e,f,g,h,i,my_logical
where a,b,c.... are initialized to 0.0d0

You are telling IDL to read just one 14-digit float, followed by one
character. That will be the first number, followed by the "0" that
happens to be the character at position 15. That in itself would not
cause that error, though presumably is not what you want, since the
logical variable is printed at the end of the line. Do you want to
read all 9 numbers, plus the logical value, or just one, skip the
middle columns, then the logical value?
I am guessing you read statement is in some loop, so that it kept
trying to read, and reached the end of the file. If you show it, it
may become clear why this is failing.

For information, here is how i wrote the file in fortran:
write(my_unit,'(9e14.6,L1)') a,b,c,d,e,f,g,h,i,my_logical
Then, how to read a L1 format in IDL?
thanks
