Ok, sorry, here we go:

driver
THE FOLLOWING NAMES ARE UNDEFINED:
 IHECLTB
IHE012I  U    &Â ABENDED IN STMT 00008 AT OFFSET 000B6E FROM ENTRY POINT
 DRIVER WITH CC 15A (SYSTEM)
DMSABN148T SYSTEM ABEND 15A CALLED FROM 7F5502.
CMS
global txtlib plilib
Ready; T=0.01/0.03 13:11:06
driver
Ready; T=0.01/0.03 13:11:10
filedef sysprint term
Ready; T=0.01/0.01 13:11:21
driver


       5                       6                      11
Ready; T=0.01/0.03 13:11:22


the first driver call is immediately after LOGON, and it ABENDs with SYSTEM 15A.

the second one works well (after GLOBAL TXTLIB PLILIB), but since there is no
FILEDEF for SYSPRINT, the output goes to a disk file.

the third one shows the output on the terminal.

My opinion was that the generated module (like a load module in MVS) contains
all the code needed to run the application. But this seems not to be the case;
the module needs the GLOBAL TXTLIB anyway, and the PL/1 runtime objects are
fetched from there at runtime, is this true? Or: does the MVS / CMS analogy not
apply?

Kind regards

Bernd
