>>---DELSTR(string,n -+-----------+-)------>< +--,length--+
DELSTR deletes the substring of string that begins at the nth character, and is of length length. If length is not specified, the rest of string is deleted. If n is greater than the length of string, the string is returned unchanged. n must be a positive whole number.
Here are some examples:
DELSTR('abcd',3) -> 'ab' DELSTR('abcde',3,2) -> 'abe' DELSTR('abcde',6) -> 'abcde'
