    Hi Squeak,

     

    You can use string map to strip the double quotes.

    set strip_quotes [string map {\" {}} $parse_user]

     

    Kind regards

Hi Squeak,

http://www.tcl.tk/man/tcl8.5/TclCmd/Tcl.htm#M24

"If a backslash (“\”) appears within a word then backslash substitution occurs." -> "This allows characters such as double quotes, close brackets, and dollar signs to be included in words without triggering special processing."

In this example, we've substituted double quotes with an empty space {}. You can alternatively use double quotes for the second parameter:

set strip_quotes [string map {\" ""} $parse_user]

Kind regards

Ben
