Is it possible to add command to CHK file to run the notebook (F5) ...

Yes - see the command WRITENOTE

Example from help file : V10 AFTER ENTRY IF V10 > 100 THEN WRITENOTE "Please check if the value @V10 in field V10 is really true" ENDIF IF V10 > 110 THEN WRITENOTE "Unusual value of field V10 is entered. Please specify reasons for this value:" SHOW ENDIF END END

to unconditionally open the entry: writenote show the example above will add the note, but not open the xxx.not file.
