Re: Basic mod-perl question : why my variable is undefined ?

Your reported output lgeX <<>> does not match any of the I/O lines in your provided code. Are you perhaps confusing the $lig variable with something else?

Why is $lig a variable if you never change its value? Why not declare it as a constant instead? If its value does change (from 4) why have you not shown that code?

Update note: The OP has now removed the reference in the parent node to "lgeX" in the output.

Thank you. Well, there is no mistake. You see lgeX<<>> because $lig is not correct and seems to be undef. I have simplified the code. In fact $lig is incremented in xxxx().	[reply]

Perhaps I have not been clear enough. The string "lgeX" appears in your reported output but does not appear anywhere in your provided code. Can you explain that, please?	[reply]

You were very clear, it was my mistake. I correct now.	[reply]
