Hi John,

Basically you are not using IO redirection correctly to read a file.
You really need to do one of the following:

1. make OTEMP a msg file, that way each read is destructive.
2. use the PRINT command to read and write a single record into
another temp file, then INPUT that file into your variable.
3. use alternate entry point that read from stdin.  Redirect
this entry point to the OTEMP file.

There are details of these approaches on Jazz at:

See slides 19-23.
