Synopsis

sbContainsAllCHars(sString, sChars, [bIgnoreCase])

Description

sbContainsAllChars retuns True if all characters given in sChars exist in sString as often as given in sChars, False if not.

Example

See graphic above

Options

sString String in which all characters will be searched.

sChars Characters which need to appear in sString. Note that characters can be stated more than once, then they need to appear as often in sString as in sChars.

bIgnoreCase Optional - standard value is False if not provided True - takes the summands as they are False - works on the summands' percentages to make all percentages add up to 100% exactly

bDontAmend Optional - standard value is False if not provided True - Function treats alls String as upper case False - Function is case sensitive
