Convert() only converts character-by-character, so the function you specified would generate ">" not ">=". You need the pxEreplace() function.

Parameterize all pathnames. Linux identifier names are case sensitive; Windows identifier names are not. Compiler and linker options are different so beware if constructing Build stages, or using compiler overrides in the Transformer stage.

Just a few of the top of my head.

When you get up to Match, you will find that both match stages require frequencies as input. So you have to generate them if for this reason alone. The test results database drives the interactive Match Designer test utility. You need to have created this database and an ODBC connection to it. What ...

Verify the input pattern that is generated. For example +// if there is only one word in the name. Parse the first token into PrimaryName and drop the two / tokens.

Set the variable in the environment of the user under whose identity the job actually runs when it's run from Designer.

To discover this identity, include a before-job subroutine ExecSH to execute an id command.

You might also consider

Code: Select all

Field(InLink.TheString, "/", 3)
if the format you gave is consistent. This expression is appropriate for the parallel or BASIC Transformer stages.

If you use a BASIC Transformer stage you have

Code: Select all

MatchField(InLink.TheString, "0X0N", 2)
as a complete solution.

Spend some time learning how parallel jobs are constructed and executed at run time. The Conductor process composes the "score" (another osh script) by combining the generated osh from the job design with information from the current parallel execution configuration file. During this proce...
