Arguments

expression—String expression that contains the substring to replace

find—Substring being searched for

replacewith—Replacement substring

start (used with count)—Position within expression where the substring search begins (If start is omitted, 1 is assumed.)

count (used with start)—Number of substring substitutions to be performed (If count is omitted, the default value is -1; thus, all possible substitutions occur.)

compare—Numeric value that specifies the kind of comparison to use when substrings are evaluated (If compare is omitted, the default value is 0; thus, a binary comparison is performed.)
