nested informat statements

[alegarra]

I have a read statement of the kind

read(1,'(a20,87510(1x,a1))') id(i), snp(i,:)

which fails to read in ifort (it reads beyond the end of the line) but reads nicely in gfortran.

Reading with

read(1,'(a20,a175020') id(i), bigword

works nicely.

I have checked my data files over and over and I am certain they are correct. Is there any limit to the size of nested informats as the one above?

Using ifort 12.1.2 20111128

Thanks
Andres

There are limits but you are nowhere near them. Please provide a tarball with a test program and sample data file that we can look at.
