How to identify the specific error indicated by a bug icon in Attachmate EXTRA! X-treme’s macro editor?
I’m writing a script in Attachmate EXTRA! X-treme using its in-application macro editor (Extra Basic), but I’m encountering a compilation error. When I run the code, I receive the message: ‘This macro cannot run because it failed to compile.’ I’ve noticed a little red bug icon next to a specific line of code, and code without these icons runs successfully.
The issue is that clicking or hovering over the bug icon doesn’t provide additional information about the error, and I can’t locate an error or warnings window. The help button in the Attachmate toolbar doesn’t provide useful documentation.
Here’s an example of the problematic code:
Sub Main
Dim Sys As Object, Sess As Object
Dim names As String
Dim bdays() As String
' Initialize session
Set Sys = CreateObject("Extra.System")
Set Sess = Sys.Sessions.Item(1)
Sess.Activate
' Getting names
names = "Annie Bella Carter"
names = Split(Trim(name_list), " ") '
ReDim bdays(UBound(names)) ' bug icon here
End Sub
How can I determine what specific error is causing the bug icon to appear next to the ReDim bdays(UBound(names)) line?
The bug icon in Attachmate EXTRA! X-treme’s macro editor indicates a compilation error that prevents your macro from running. Since hovering over the icon doesn’t provide details, you need to use systematic debugging approaches to identify the specific issue.

Common Causes of Bug Icons
The red bug icon typically appears for several reasons in EXTRA! X-treme’s macro editor:
Syntax Errors: Missing or incorrect syntax, unmatched parentheses, or invalid function calls
Variable Issues: Undeclared variables, type mismatches, or scope problems
Array Problems: Improper array dimensioning or bounds errors
Function Failures: Built-in functions returning errors or invalid results
In your example code, the issue likely stems from the line names = Split(Trim(name_list), " ") where you’re referencing name_list but the variable was declared as names.
Debugging Techniques for EXTRA! Basic
Since the built-in help system has known issues (as mentioned in the Tek-Tips discussion), you need alternative debugging approaches:
1. Breakpoint Debugging
Set breakpoints by clicking in the margin next to line numbers to step through code execution:
Sub Main
Dim Sys As Object, Sess As Object
Dim names As String
Dim bdays() As String
' Initialize session
Set Sys = CreateObject("Extra.System")
Set Sess = Sys.Sessions.Item(1)
Sess.Activate
' Debug: Check if name_list exists
Debug.Print "Variable before Split: " & name_list
names = Split(Trim(name_list), " ")
Debug.Print "After Split - Array size: " & UBound(names)
ReDim bdays(UBound(names))
End Sub
2. Immediate Window Testing
Use the Immediate Window (Ctrl+G in some versions) to test individual expressions:
? Trim(name_list)
? Split("Annie Bella Carter", " ")
3. Error Handling with MsgBox
Add diagnostic message boxes to identify where the error occurs:
Sub Main
On Error GoTo ErrorHandler
Dim Sys As Object, Sess As Object
Dim names As String
Dim bdays() As String
' Initialize session
Set Sys = CreateObject("Extra.System")
Set Sess = Sys.Sessions.Item(1)
Sess.Activate
' Check variable existence
If name_list = "" Then
MsgBox "name_list is empty!", vbExclamation
Exit Sub
End If
names = Split(Trim(name_list), " ")
MsgBox "Split successful. Array size: " & UBound(names)
ReDim bdays(UBound(names))
Exit Sub
ErrorHandler:
MsgBox "Error " & Err.Number & ": " & Err.Description & vbCrLf & _
"Occurred at line: " & Erl(), vbCritical
End Sub
Analyzing Your Specific Code Example
Looking at your code, I can identify several specific issues:
Primary Issue: Variable Name Mismatch
names = Split(Trim(name_list), " ") ' References name_list
The variable names is declared but you’re trying to assign the result of splitting name_list, which is never defined.
Secondary Issues:
- Array ReDim without proper initialization: The
ReDimstatement depends onnamesbeing a valid array from the Split operation - Missing error handling: No validation that the Split operation succeeded
Corrected Version:
Sub Main
Dim Sys As Object, Sess As Object
Dim name_list As String ' Correct variable name
Dim names() As String ' Should be array type
Dim bdays() As String
' Initialize session
Set Sys = CreateObject("Extra.System")
Set Sess = Sys.Sessions.Item(1)
Sess.Activate
' Correct variable name and assignment
name_list = "Annie Bella Carter"
names = Split(Trim(name_list), " ")
' Now ReDim will work properly
ReDim bdays(UBound(names))
End Sub
Step-by-Step Error Resolution Process
Follow this systematic approach when encountering bug icons:
-
Check Variable Declarations
- Ensure all variables are properly declared
- Verify variable names match throughout the code
- Confirm variable types are appropriate
-
Test Individual Lines
- Isolate problematic code sections
- Test expressions in the Immediate Window
- Use message boxes to display intermediate values
-
Enable Error Handling
vbOn Error Resume Next ' Temporarily ignore errors ' Test problematic line here If Err.Number <> 0 Then MsgBox "Error: " & Err.Description Err.Clear End If On Error GoTo 0 ' Reset error handling -
Consult Documentation
- As noted in the Tek-Tips forum, the built-in help may not work
- Use external resources like the EXTRA! Basic documentation
-
Search Known Issues
- Check forums for similar error patterns
- Look for version-specific bugs in EXTRA! X-treme
Best Practices for Error Prevention
1. Defensive Programming
Sub SafeMacro()
On Error GoTo ErrorHandler
' Validate inputs before processing
If IsEmpty(name_list) Or name_list = "" Then
MsgBox "Input data is empty", vbExclamation
Exit Sub
End If
' Process with error checking
Dim names() As String
names = Split(Trim(name_list), " ")
' Check if Split returned valid array
If IsArray(names) And UBound(names) >= 0 Then
ReDim bdays(UBound(names))
Else
MsgBox "Failed to create name array", vbExclamation
Exit Sub
End If
Exit Sub
ErrorHandler:
LogError Err.Number, Err.Description, "SafeMacro"
MsgBox "Macro failed: " & Err.Description, vbCritical
End Sub
2. Proper Array Handling
As discussed in the MicroFocus community, array dimensioning requires careful attention:
' Safe array initialization
Dim tempArray
tempArray = Split("Annie Bella Carter", " ")
If IsArray(tempArray) Then
ReDim bdays(UBound(tempArray))
Else
' Handle error case
ReDim bdays(0) ' Minimum size
End If
3. Version-Specific Considerations
From the support documentation, different versions of EXTRA! X-treme may have different behaviors:
- Version 8.0 has known help system issues
- Version 9.0+ includes improved productivity features
- Always test macros in the target environment
Advanced Debugging Resources
When basic debugging doesn’t reveal the issue, consider these advanced approaches:
1. External Debugging Tools
- Use Windows Script Host for more detailed error reporting
- Implement logging to external files
- Consider using Excel VBA debugging when integrating with Excel (as mentioned in MrExcel discussions)
2. Community Support
- Tek-Tips Forums: Active community for EXTRA! X-treme issues
- MicroFocus Community: Official support from the current maintainer
- Stack Overflow: General programming questions (as seen in this discussion)
3. Documentation References
- EXTRA! Basic Language Reference: Official syntax and function documentation
- Migration Guides: For upgrading between versions
- API Documentation: For object model references
The key to resolving bug icon errors in EXTRA! X-treme is systematic debugging, proper error handling, and leveraging community resources when the built-in tools fall short.

Conclusion
Identifying specific errors indicated by bug icons in Attachmate EXTRA! X-treme requires a systematic debugging approach:
- Check basic syntax and variable names first, as simple mismatches are common causes
- Use error handling and message boxes to isolate problem areas when hovering doesn’t work
- Test expressions individually in the Immediate Window to pinpoint exact failures
- Leverage community resources when built-in help fails, as noted in multiple forum discussions
- Implement defensive programming with proper validation and error checking
For your specific code example, the issue appears to be a variable name mismatch where name_list should be names. Always validate that array operations succeed before using their results in dimensioning statements. If you continue to experience compilation errors, consider posting your specific code to the Tek-Tips or MicroFocus communities for more targeted assistance.
