Tcl's only data type is the string, and each command can interpret strings in special ways.[6]A list is a special interpretation of a string—a list of words separated by whitespace. Lists are a very powerful feature of Tcl: they are easy to visualize and can be formed from simple str...
Tcl lists are just strings with a special interpretation. Separated by white space or grouped with braces or quotes. tcl> set mylist "a b {c d}" tcl> set mylist [lista b {c d}] ;# same as above tcl>for eachelement $mylist {puts $element} abc d Here several Tcl commands relate...

-integer 把list的元素转换成整数,按整数排序. -real 把list的元素转换成浮点数,按浮点数排序. -increasing 升序(按ASCII字符比较) -decreasing 降序(按ASCII字符比较) -command command TCL自动利用command 命令把每两个元素一一比较,然后给出排序结果。 List split命令语法:split string splitChars 把字符串string...
disposed or modified. In embedded systems memory management can be complex, so all operations with Tcl values are moved into isolated functions that can be easily rewritten to optimize certain parts (e.g. to use a pool of strings, a custom memory allocator, cache numerical or list values to...
