Variable assignment, do loops, and put statements

[Seth Olsen]

I have been attempting to run a deck that has the following loosely outlined code

do i=7,9
do j=9,1,-1

!***electronic structure code outputting natural 
!***orbitals to record 2141.1 


filename='ac22s2s10_hwag$i$j'
moldenfile='$filename.molden'
orbfile=$filename.orb'

put,molden,$moldenfile,orb,2141.2
matrop
load,orbitals,orb,2141.2
write,orbitals,$orbfile,new

enddo
enddo


However, when I run the code the names of the written files include spaces where i did not intend them to be for example, the molden file is 'ac22s2s1i0_hwag12  .molden' , with spaces before the suffix that confuse the shell I'm working with and cause me stress.  Does any body know what I'm doing wrong?  Thanks.
