Hi Eric,

Then READE should operate via the same mechanism then, and have similar
response time.  If it does not, it is at best, an implementation
deficiency.

See QDEVTOOLS/QRPGLEMSG, message ID RNF7092, which indicates that READE,
READP, and READPE cannot block.  (Scott K highlighted this one in an
earlier post.)

Why should it be that SETLL+READ can block, but SETLL+READE cannot?

Regards,
Rich
