compare_realcols utility

This SAS routine allows to compare real columns from two files, with absolute and relative tolerance. It ends in error whenever two values don't match.

The calling sequence is:

compare_realcols table=newfile(:table) reftable=reffile(:table) 
                 colnames="column list" (abstol=tol1 reltol=tol2 operation=op)

# newfile(:table): name of the first  file with table (first by default)
# reffile(:table): name of the second file with table (first by default)
# "column list"  : names of the columns to be compared (separated by a blank)
# tol1           : absolute tolerance on difference (1E-4 is default)
# tol2           : relative tolerance on difference (1E-4 is default)
# op             : OR (default) to apply the less stringent of both tests
                   AND          to apply the most stringent of both tests
