Hi Li Mei,

I did some testing using PB 2017 R2, build 1756 gradually extending the length of LibraryList string. I found the issue still exists.

When the application crashes, it crashes silently. Neither Application.Close nor Application.SystemError executes.

Question remains: How many files does anyone need in the LibraryList in case 500 files is too few? ...

Actually, my library list only contains 5 different file names, I just repeat one of the files again and again.

I have never specified SetLibraryList () with an array variable definition, and I've used this function quite often.

I have always built a string with the PBLS required, then specified that one string as the parameter to the function.

Example:   ls_libraries = "library1.pbl, library2.pbl, library2.pbl, .....libraryN.pbl"

        OR    ls_libraries = getlibrarylist ()
                 ls_libraries =ls_libraries + "library1.pbl, library2.pbl, .....libraryN.pbl

       THEN   SetLibraryList (ls_libraries)

With this technique, I've never reached any size limitation of the function.

Try your code in this manner:

Create your array as usual
Create a master string to hold the final library list: ls_libraries
Populate your array
Using the TRIM function, copy the data from the array into the string "ls_libraries"
Use the string "ls_libraries" as the parameter to the SetLibraryList() function ---> SetLibraryList (ls_libraries)
