Hi I dealt with this issue a couple of months ago. I too wanted to
transfer an array data from IDL to Fortran for processing and pass it
back.
I simply wrote an outfile from IDL, which fortran uses as an input
parameter file.And it worked well for me.
Here is what i did:

forprint,result,text='data.prt',/silent,/nocomment ;The variable
result contains the array that are the inputs of fortran and
these ;are stored in a file data.prt.

spawn,['./fortran.f'],/noshell, result ;Here the variable result
contains the output from fortran. I used the no shell keyword
to ;increase the speed.

Hope it was useful,

regards,
vino
