And I found out how I misled myself. In fact:
//SYSTSIN DD *
transmit host.user ddname(INDD) outddname(OUTDD)
//INDD DD DISP=SHR,DSN=SYS1.MACLIB(SPLEVEL)
does transmit the entire library. I suppose it has ever been thus;
I likely simply never tried it. However, by experiment:
transmit host.user dsn('SYS1.MACLIB(SPLEVEL)') outddname(OUTDD)
... transmits only member SPLEVEL, in IEBCOPY unloaded format. Words
can not express how I feel about all this. But Charles and Radoslaw
might make a good guess.
