NAME<\/a> ______________________________________________________________________________<\/p>\n global \u2212 Access global variables<\/p>\n global<\/b> ?varname …<\/i>? ______________________________________________________________________________<\/p>\n This command has no effect unless executed in the context of a proc body. If the global<\/b> command is executed in the context of a proc body, it creates local variables linked to the corresponding global variables (though these linked variables, like those created by upvar<\/b>, are not included in the list returned by info locals<\/b>).<\/p>\n If varname<\/i> contains namespace qualifiers, the local variable\u2019s name is the unqualified name of the global variable, as determined by the namespace tail<\/b> command.<\/p>\n varname<\/i> is always treated as the name of a variable, not an array element. An error is returned if the name looks like an array element, such as a(b)<\/b>.<\/p>\n This procedure sets the namespace variable ::a::x<\/i><\/p>\n proc reset {} { This procedure accumulates the strings passed to it in a global buffer, separated by newlines. It is useful for situations when you want to build a message piece-by-piece (as if with puts<\/b>) but send that full message in a single piece (e.g. over a connection opened with socket<\/b> or as part of a counted HTTP response).<\/p>\n proc accum {string} { namespace(n), upvar(n), variable(n)<\/p>\n global, namespace, procedure, variable<\/p>\n global \u2212 Access global variables <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3783,1],"tags":[2828,2635],"class_list":["post-6195","post","type-post","status-publish","format-standard","hentry","category-n-comandos-tcl-tk","category-sin-categoria","tag-global","tag-mann"],"gutentor_comment":0,"_links":{"self":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/6195","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/comments?post=6195"}],"version-history":[{"count":0,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/6195\/revisions"}],"wp:attachment":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/media?parent=6195"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/categories?post=6195"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/tags?post=6195"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
