NAME<\/a> ______________________________________________________________________________<\/p>\n for \u2212 \u2019For\u2019 loop<\/p>\n for<\/b> start test next body<\/i> ______________________________________________________________________________<\/p>\n For<\/b> is a looping command, similar in structure to the C for<\/b> statement. The start<\/i>, next<\/i>, and body<\/i> arguments must be Tcl command strings, and test<\/i> is an expression string. The for<\/b> command first invokes the Tcl interpreter to execute start<\/i>. Then it repeatedly evaluates test<\/i> as an expression; if the result is non-zero it invokes the Tcl interpreter on body<\/i>, then invokes the Tcl interpreter on next<\/i>, then repeats the loop. The command terminates when test<\/i> evaluates to 0. If a continue<\/b> command is invoked within body<\/i> then any remaining commands in the current execution of body<\/i> are skipped; processing continues by invoking the Tcl interpreter on next<\/i>, then evaluating test<\/i>, and so on. If a break<\/b> command is invoked within body<\/i> or next<\/i>, then the for<\/b> command will return immediately. The operation of break<\/b> and continue<\/b> are similar to the corresponding statements in C. For<\/b> returns an empty string.<\/p>\n Note: test<\/i> should almost always be enclosed in braces. If not, variable substitutions will be made before the for<\/b> command starts executing, which means that variable changes made by the loop body will not be considered in the expression. This is likely to result in an infinite loop. If test<\/i> is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iteration), so changes in the variables will be visible. See below for an example:<\/p>\n Print a line for each of the integers from 0 to 9:<\/p>\n for<\/b> {set x 0} {$x<10} {incr x} { Either loop infinitely or not at all because the expression being evaluated is actually the constant, or even generate an error! The actual behaviour will depend on whether the variable x<\/i> exists before the for<\/b> command is run and whether its value is a value that is less than or greater than\/equal to ten, and this is because the expression will be substituted before the for<\/b> command is executed.<\/p>\n for<\/b> {set x 0} $x<10 {incr x} { Print out the powers of two from 1 to 1024:<\/p>\n for<\/b> {set x 1} {$x<=1024} {set x [expr {$x bodies manpages.csv script_extrae_body.sh script.sh usr 2}]} { break(n), continue(n), foreach(n), while(n)<\/p>\n boolean, for, iteration, loop<\/p>\n for \u2212 \u2019For\u2019 loop <\/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":[2938,2635],"class_list":["post-6354","post","type-post","status-publish","format-standard","hentry","category-n-comandos-tcl-tk","category-sin-categoria","tag-for","tag-mann"],"gutentor_comment":0,"_links":{"self":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/6354","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=6354"}],"version-history":[{"count":0,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/6354\/revisions"}],"wp:attachment":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/media?parent=6354"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/categories?post=6354"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/tags?post=6354"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
