Yes, TSOLIB is part of TSO/E and is correctly implemented by ATTACHing subsequent commands with a TASKLIB. The TSO/E developer who was designing TSOLIB wanted to do an incorrect, dangerous thing like STEPLIB did, so that he could provide equivalent function to STEPLIB. Peter Relson, Karl Schmitz, and I did not allow him to do that.
STEPLIB was created by Art Breslau, who worked for IBM, but not in the MVS or TSO development organization. STEPLIB may have been an FDP (Field Developed Program). Mr. Breslau had a bit of a bad reputation with our development organization because of the unsupported and dangerous things that he did in his "products".
