Thanks, Mark, for your suggestion about FCOPY.
If possible I dont't want to retransmit this 30 MB Files (compressed!)
over Internet again.
So if there is a way I would prefer to convert the byte stream file now
on the target
MPE 5.5 system into a new file with the original '2048 bytes per record'
.
See below what I tried ...

This is the 'byte stream' file I want to convert :
FILENAME CODE ------------LOGICAL RECORD----------- ----SPACE----
SIZE TYP EOF LIMIT R/B SECTORS #X MX
TF 1B BA 148727915 2147483647 1 580976 * *
I suppose the 'B' in 'BA' in the TYP column means 'byte stream'.
I build now the new file as it should be:
:build TF2;rec=-2048,1,f,binary;disc=80000
Then FCOPY:
:fcopy from=TF;to=TF2
HP31900A.05.02 FILE COPIER (C) HEWLETT-PACKARD CO. 1990
*200*WARNING: FROMFILE RECSIZE IS 8192 BYTES, TOFILE RECSIZE IS 1024
WORDS.
CONTINUE OPERATION (Y OR N) ?y
*201*WARNING: FROMFILE IS ASCII, TOFILE IS BINARY
CONTINUE OPERATION (Y OR N) ?y
EOF FOUND IN FROMFILE AFTER RECORD 1
2 RECORDS PROCESSED *** 0 ERRORS
END OF SUBSYSTEM
:listf TF2,2
ACCOUNT= TEST GROUP= PUB
FILENAME CODE ------------LOGICAL RECORD----------- ----SPACE----
SIZE TYP EOF LIMIT R/B SECTORS #X MX
TF2 1024W FB 2 80000 1 256 1 *
Well, that's not exactly what I wanted .... 2 records instead about
72'000 ...
Any other suggestion?
Thanks for helping.
Kurt
