ContainsOnly compares the contents of the subject string against the characters supplied in the String parameter and returns a True if no other characters are found in the subject.
In the sample below, the string is tested to ensure that it only contains the digits 0 through 9 and a blank. If other characters are used in #String, the function returns False.
#Save.Enabled := #String.ContainsOnly( " 0123456789" )
