I hope I've posted this request to appropriate groups, I included
Pascal because that's the target language but I can read C, FORTRAN,
etc.  I need a way to count the number of typos by comparing a sample
string with a target string.  I'm not sure how smart UNIX 'diff' is,
but I would think the problem is analagous: you wouldn't want to
declare two files completely different because one was preceeded by an
extra blank line.

For example,

target: run Spot run.

sample 1 (1 error): ruyn Spot run.
sample 2 (2 errors): rnu Spot run.
sample 3 (2 errors): runnm Spot run.
and, incidentally,
sample 4 (1 error): run spot run.

I would appreciate any suggestion.  Thanks very much.
