Because of the keywords, I need to read each line in as text first and test if it’s a keyword, and then call the appropriate subroutine based on the keyword value. Within the subroutines I also need to read each line as text first so I can stop the subroutine when the next keyword is found.

If I were able to read directly from the input file, then a simple formatted read statement does everything I need. But if I am reading from a string, then things get a bit more complicated.

Hi Robert,

This may be a known bug. It sounds familiar. Let me do some checking.

Fortranners, if I confirm this is the bug I think it is, I think I can 
squeeze some time to fix it.
