User-Defined Function: string uStringReverse( string vStrSrc );

Returns a string that is vStrSrc with the characters in reverse order

  • vStrSrc: source string to reverse

Caveats

  • The "Faster" version doubles the string size internally, and is more likely to cause a stack/heap collision(script crash) with large strings and/or limited free memory
