powershell - Setting multiple global variables within functions -

i have multiple global variables in script use within function.

$global:row_array = @(); $global:column_array = @(); $global:sorted_array = @(); $global:totalrows = 0; $global:array=@(); $global:m_file;  # button click event handler... $run_it.add_click({     for($i=0; $i -lt 6; $i++){         $global:row_array += $i     }     ...     ...  }) 

now need put $global: qualifier in front of every global variable inside event handler?

or can this:

$run_it.add_click({     for($i=0; $i -lt 6; $i++){         row_array += $i     }     ...     ...     # @ end...     $global:row_array = $row_array;     $global:column_array = $column_array;     $global:sorted_array = $sorted_array;     ... }) 

i can global replace in editor of variables , put $global: in front wanted know if there more elegant way. ref keyword problematic? also, whether functions using global variables idea or not separate discussion… using temporary project.
