[netrexx-pipelines] NetRexx runtime Return Code

[Marc R. <re...@gm...>]

Hi Jeff,

a NetRexx program returns the value specified by an 'exit' clause when run.
The translator returns any of the following :
    EXIT_OK     =int 0          -- Exit values
    EXIT_WARN   =int 1          -- Exit values
    EXIT_ERROR  =int 2          -- Exit values

I've reproduced your issue, this 'RC=16' comes from the run method in specj.
Above this method, there is the comment 'The run method of specs should never get called'

Not being familiar with pipelines, I don't know why this method is not be called, nor why it is called when having a local class generated without package statement.
To fix your issue and test your new specj stage, leave the package statement as is and rebuild the NetRexxC/F.jar ('ant' from netrexx-code directory) to have the specj class properly 'packaged' ;

$ pipe 'literal one two three | specj word -2 1 | console'
two
