Rewind Stop Code & Alias -- The Rewind Stop Code field is to contain the character that will be output at the beginning of the machine control data file (usually '=') representing the rewind stop code. The Rewind Stop Code Alias is a string that will be output wherever a rewind stop character is required (8 ASCII characters max). Note: see PLABEL option 63 if blank characters are to be part of the alias. (Intcom 1841)
