APPEND or MAPJOIN all coverages in a workspace without typing the coverage names

Summary

When you need to combine all the coverages in a workspace, with APPEND or MAPJOIN, you can avoid typing each coverage name by using the [LISTFILE] function to create an ASCII file that lists the coverage names. You can use this ASCII file as input to the APPEND or MAPJOIN command.

Procedure

1. Use the [LISTFILE] function to create the ASCII file that lists the coverages in your workspace. In this example, covlist.txt is the ASCII file.
   
   

   Code:
   Arc: &ty [listfile * -cover covlist.txt]

   
   
2. Run the APPEND command and provide the name of the ASCII file with the following syntax when prompted to enter the first coverage name.
   
   

   Code:
   Arc: append outcov
   Enter Coverages to be APPENDed (Type END or a blank line when done):
   =======================================
   
   Enter the 1st coverage: &run covlist.txt
   Enter the 4th coverage:
   Done entering coverage names (Y/N)? y
   Do you wish to use the above coverages (Y/N)? y
   
    Appending coverages...

   
   
3. Delete the ASCII file, if you wish.
   
   

   Code:
   Arc: &ty [delete covlist.txt -file]
