"how the evaluation of the variable /sockread works ?"
/sockread is NOT variable - it's an alias. You can see this because it begins with a / and not with a % (or sometimes a &). Therefor you can not evaluate it, since that is limited to variables and identifiers (those thingies that start with a $)
If you had read the helpfile or read a tutorial, you would know that /sockread %varname dumps the information the socket receives into the variable by the name %varname. From there on, it's a normal variable and you can do whatever the heck you want with it.
Now if this still isn't the answer you want, then think long and hard about how you phrase your questions, as quite obviously -- judging from the lack of response -- none of the scripters on this board understand what you mean then.
