This function doesn't seem to work in my version. It isn't recognized as a command.
Looks like we missed that one in the command list. When we next update the players on the various stores it should be fixed.
Also how do I delimit strings in a file so readstring can get them?
You can use WriteString() to write strings that are automatically delimited, if you write three strings it will take three calls to ReadString to reach the end of the file. Alternatively if you want to edit the file manually then the format for strings is the first 4 bytes are an integer holding the length of the string, then X number of bytes of string data where X is the value held in the integer. This then repeats for as many strings as you want to add. int, data, int, data, etc
