$insert(<num> <word> <text>)

• The <word> argument is a dword which is different from most function arguments.
• If the <num> integer argument is omitted the empty string is returned.
• If the <word> argument is omitted the empty string is returned.
• The return value of this function is <text> with the <word> argument inserted after the <num>th character.

This function can be used to insert text into the middle of a string at a known location. You probably found the location by using $index() or $rindex().
