[ARexx] Error while counting icons (bug?)

[mateusz_s]

Hi,
When the drawer is empty or nothing is visible (because lack of icons)
I got error when using:

GETATTR WINDOW.ICONS.SELECTED.COUNT NAME file_path VAR selected_icons_count;
or
GETATTR WINDOW.ICONS.ALL.COUNT NAME file_path VAR all_icons_count;

If there are some files but without icons and I choose Show All Files - script works ok.

The whole script looks like this:

/*  
    $VER: myTextEdit with selected icon (v1.0)
*/

ADDRESS workbench;

GETATTR WINDOWS.ACTIVE VAR file_path;

/* errors here */
GETATTR WINDOW.ICONS.SELECTED.COUNT NAME file_path VAR selected_icons_count; 

file_path_length$ = LENGTH(file_path);
is_slash$ = '/';
IF (SUBSTR(file_path, file_path_length$) = ':') THEN is_slash$ = '';

IF (selected_icons_count = 0) THEN
    ADDRESS COMMAND 'sys:Tools/TextEdit ' file_path || is_slash$ || 'new_text_file.txt';
ELSE DO
    GETATTR WINDOW.ICONS.SELECTED.0.NAME NAME file_path VAR file_name;
    ADDRESS COMMAND 'sys:tools/TextEdit ' file_path || is_slash$ || file_name;
END;

EXIT;

What error do you get and did you use trace to find errors?

Hi,
It returns me code nr 10.
It my very first Arexx script ever, I don't know how to trace it.

Check this: https://wiki.amigaos.net/wiki/AmigaO...Rexx_Debugging and ARexxGuide2 on Aminet.

I usually put a "trace i" somewhere in the script, start TCO (trace console) and then launch the script. Trace output should be visible in the trace console.
