PASSWORD is not the last keyword on the JCL JOB statement.
The template JCL contains a %PWD symbolic, but the line does not specify // PASSWORD=%pwd.
No other keywords can follow the PASSWORD keyword so a pass phrase sized at 66 bytes can be used in net port JCL without exceeding the z/OS 80 byte JCL limit.
PowerExchange does not submit the net port or Db2 loader job.
In the template JCL, ensure that the PASSWORD keyword is the last keyword on the JOB statement and it starts at position 4.
