Considering that the only code you show after the 'DEBUG 1' is a comment and closing brace, I'm going to have to guess that the problem lies elsewhere in your code.

We can't diagnose what we can't see.

Hia again roboticus,

Yes I know, but the script ~3000 lines, with homemade modules, so it's no easy to make a small working example

The question is general : a script is executed sequencely (right ?), how can my script hang after my print statement without printing my DEBUG ?

I found where the script hangs, but don't know why.

if ( $concerne1_param_name ne '' ) {

    $cnt++;
    $line++;
    $Sheet->Cells( $line , 4 )->{Value} = $concerne1_param_name;
}


if ( $concerne2_param_name ne '' ) {

    print h2( "DEBUG 2 : \$line -> $line : \$cnt -> $cnt " );

    $line++;
    $cnt++;
    $Sheet->Cells( $line , 4 )->{Value} = $concerne2_param_name;
}

The script hangs in the second if block, even if the block is empty :

if ( $concerne2_param_name ne '' ) {

}

the last ( browser ouput) is :

DEBUG 0
DEBUG 1 : 119
DEBUG 2 : $line -> 26 : $cnt -> 3

if I comment the block everything works again

Any idea is welcome

Have a nice day.
