Takes one existing Source value, and two parameters, Search, NewVal
Description:
This function uses the left Source value, searches it for the SearchVal, and replaces any found occurrences with the NewVal parameter.
This function is case insensitive, and each parameter may be any number of bytes in length. Because of this flexibility, this command is an order of magnatude slower than the byte-for-byte case sensitive ReplaceAny$ function.
Example:
[New] searchVal = "ab"
[New] newVal = "y"
[New] source = "abc"
source = Replace$ searchVal, newVal
Html source 'Result is equal to "yc"
