Parameters


Parameter	Meaning
pattern	pattern
number	number to be checked

Return value

The function returns TRUE if the range is correct otherwise, FALSE.

Description

Using the function numberMatch(), you can check whether the number number falls in the range that is described by the pattern pattern.

main()
{
  bool isTrue, isFalse;
  DebugN(isTrue  = numberMatch("1, 3, 6 - 9", 7));
  DebugN(isFalse = numberMatch("-9 - -6, -3, -1", 7));
