Hello, Is there a way to make ruby interpret a string as a set of command? for example action="p this is test one" action.command action="for i in 1..4 p this is test two end" action.command and have the out put be this is test one this is test two this is test two this is test two this is test two I am working with TK gui and want to create a general popup menu fuction, but i need to set the commands for differnt menus.

Also, eval has certain security implications, especially with user-supplied strings forming part of the eval-ed code. If you want to make general popup menus, I'd personally use a proc instead of a string to specify the action, because you might run into passing around bindings with your strings real soon for non-trivial event handlers, and jagged blades and boggy swamps await that way. Or perhaps not. David V.
