On THE 3.3B1 WinXP with REXX-Regina_3.3(MT) 5.00 25 Apr 2004
too often when tracing (trace ?i) someting like COMMAND LOCATE or COMMAND READV (haven't examined all commands) does not set RC. RC is left as the string "RC", which plays havoc trying to determine if the command succeeded. Without tracing, RC seems to be set properly.
