When using the COMPOSER command to run a Processing Sequence, you can submit the command to batch. For example, you could use a command like this to submit the supplied processing sequence TUT_01_P1 to run in batch :
SBMJOB JOB(TUT_01_P1)
CMD(<pgmlib>/COMPOSER REQUEST(RUN)
PSEQ(TUT_01_P1)
PARMS((YOURINITIALS 'FS')
(YOURMESSAGE 'Hello World')
(YOURNAME 'Fred Smith')))
(where <pgmlib> is the name of the program library for the LANSA system in which LANSA Composer is installed).
