But does mere mention of OPTCD=Q mean its use is restricted to tapes?
Might not it apply to other device types? (It's hard to prove a negative)
But if it's so restricted it's another instance of IBM's implementing a
useful facility at the wrong layer. ASCII<->EBCDIC conversion is surely
useful on other device types.
Is this software in the OS or microcode in the control unit?
And what about CCSID. According to the documentation, this:
//STEP3 EXEC PGM=IEBGENER,CCSID=1047
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT2 DD PATHMODE=(SIRUSR,SIWUSR),
// PATHOPTS=(OCREAT,OTRUNC,OWRONLY),
// CCSID=1209,
// PATH='&OBFUSC/work/tmp/UTF-8'
//SYSUT1 DD *
This is a UNIX UTF-8 test. cent: "ยข"
//*
... should write SYSUT2 in UTF-8, yet it seems to write EBCDIC. Or am I
overlooking yet another restriction? But at the very least, if it's supposed
to not work it should fail with an error message.
