Normally you can jump from the variable view to the definition. If a variable defined in the working section it fails. This works in the version with the button "open copy book "

Analyze code with regexp is an error-prone job. Have ever thought about a parser:

• TypeCobol use some
• Sprache seems an easy to use parser-approach

See the motivation for a JS solution.

I have canal running on my windows laptop, works fine and analyses a simple Cobol program. I have installed it on my Windows10Pro system, and it starts up immediately after install. I can load the desr program, and it shows the code but fails to display structure in the right hand pane with a Null CobolTree message. Subsequently trying to run Canal won't even start up...

I opened a COBOL program - but i get the error message that the CobolTree could not be built.
what are the next steps to understand why?

Submitter: foo
Foo

System.ArgumentException: parsing "F-MERKER(1" - Not enough )'s.

The Start-Tab doesn't close if you click on the x-button unless it's supposed to work like that?!

Hi,

The source file cannot recognize copybooks with extensions .cpy.

The picture at the readme shows a tree which is ordered by performs. (Sort by performs) This. seems to be broken in 2.8.0.0.
Furthermore it would be nice to see how much lines each method has. It makes it easier to make a forecast how much work must be done.

Exception:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

at System.ComponentModel.RunWorkerCompletedEventHandler.Invoke(Object sender, RunWorkerCompletedEventArgs e)

For example

01  FOO.                                            
    03  BAR                   PIC S9(11)V99 COMP  
                                    OCCURS 5.           

or

  01  FOO                     PIC X.                   
         88  BAR              VALUE "0", "1", "2", "3",
                                           "4", "A", "B".     

Currently, occurs before pic definitions are not properly recognized:

01  FOO.                                                  
    03  BAR                 OCCURS 10  PIC S9 COMP.

IdentificationDivision still has a parent assigned.

Can you explain how to enable the feature "Find all variables used in a procedure, and if they are input or output". Can't find it in 2.8.0
Would be a great feature

Example:

123456             COMPUTE Blubb      = Abc
123457                          * 100 / XYZ.

New Feature: If a word in the procedure xyz is marked, it would be greate if the procedure in the tree is highlighted.

The codeBox looses its focus => ctrl+c doesn't work anymore

If you look from where a procedure is called, you can use the great Referenced By- information. Unfortunately you jump to the first line of the procedure. This is uncomfortable if the procedure is long.
