5. Hidden Gems SET Parameters  Switches that affect behavior – scope varies  You can set at multiple levels  EDASPROF  Group/User Profile  Focexec  Request  Look at the difference in behavior to see when to apply them

6. Corrupt PDF Hidden Gems SET Parameters – PDFLINETERM  Truly hidden – not available currently in SET tool  To eliminate corrupt PDF files that pass through UNIX systems in distribution.  Adds additional space to account for the difference in new line indicator. SET PDFLINETERM=OFF | ON PDF UNIXUNIX

7.  &ECHO allows tracing of WebFOCUS execution  -SET &ECHO – local variable requires setting in each script  Provides setting for default value of &ECHO  Default value is used in all INCLUDEd and EXECuted fexes unless –SET issued  Trace appears in View Source window Hidden Gems SET Parameters – DEFECHO SET DEFECHO=OFF | ON | ALL | NONE

8. Hidden Gems SET Parameters – DEFECHO SET DEFECHO=OFF | ON | ALL | NONE One setting controls all – NONE – Prevents unauthorized use of ECHO. Cannot be reset OFF – No tracing of WebFOCUS stack ON – Tracing of WebFOCUS stack only ALL – Tracing of WebFOCUS stack and Dialogue Manager (including &variable substitution)

9.  Controls which DBA is applied to in JOIN structure  Default value – HOST - Applies DBA from HOST file only  Value – ALL – Applies DBA from both files if present  Access control – FILE, SEGMENT, FIELD, VALUE  DBA converted to selection criteria and optimized Hidden Gems SET Parameters – DBASOURCE XREFHOST JOIN DBA1 DBA2
