According to the standards, in awk all of the following are required to produce identical results:

angshuman,
What was the input line and what field separator were you using when \$15-\$14+1==\$11 did not give you the results you expected; or if you changed the value of \$11, \$14, or \$15 after reading the line, what values did they have when \$15-\$14+1==\$11 gave you unexpected results?
