Re: Emulated S36 pn RS/6000 to AS/400 Conversion

Kirk,

    In order to restore files from a true System/36 tape, you need to 
use the RSTS36F command.  Even in the S/36 environment, SAVE and 
RESTORE use OS/400 save format files.

    If you are using DSPTAP (without *SAVRST) to look at the save tape 
and you can't read it, then you have another problem altogether.  You 
should at least be seeing the labels.  Verify that your AS/400 tape 
drive can read the tape density that being used for the save tape.

    The advantage of using a S/36 machine is that you are object-level 
compatible with a real S/36, and it is very fast.  The downside is 
that to access S/36 files from OS/400, you have to use file transfer 
or DDM, since the S/36 appears to OS/400 as a completely separate 
machine.

    The advantage of using the S/36E is file access (see above), and 
you can begin to mix in native OS/400 commands and programs into your 
System/36 job streams.  The downside is that it is slow, and has many 
"gotchas" (like the SAVE/RESTORE thing).
