This fix applies to all versions of CHARMM through c40a2 and c39b2 (but I only checked as far back as c32b2).

Use of the following command corrupts data arrays SSKIP and STOT, and does not return correct results.

MANTIME series-name AVER integer

The file that needs to be fixed is source/correl/mantim.src

Here is the output from 'diff -u', with the fixes identified with '+', and the old code with '-'; in essence, the the variable I should be the variable L.
