/removeintchecks [+ | -]
The default for this option is /removeintchecks-, which causes the compiler to check all integer calculations for errors such as overflow or division by zero.
Specifying / removeintchecks or / removeintchecks + prevents error checking and can make integer calculations faster. However, without error checking, incorrect results may be stored without raising an error if data type capacities are overflowed.
Compile test.vb
and turn off integer overflow error checking:
vbc /removeintchecks+ test.vb
