y : z If-then-else 与C的一样 Tcl 中的逻辑真为1,逻辑假为0。 一些例子: 5 / 4.0 5 / ( 【string length "abcd"】 + 0.0 ) --- --- 计算字符串的长度 转化为浮点数来计算 "0x03" > "2" "0y" < "0x12" 都返回 1 set a 1 expr $a+2 expr 1+2 都返回 3...
string wordstart Return start position of word in string subst Blackslash,command,variable substitutions string map dictionary string # string中出现dictionary关键字置换为相应的值 -nocase 不区分大小写 string is digital 1234 #数据类型判断,ascii/boolean/double/float/integer/list/lower/alpha ->1 Tcl 有...
toupper 返回string1中的所有字符串转换为大写后的字符串 length 返回string1的长度 例子: 1 string length $qian;#将返回变量qian的长度 6.数字操作 因为tcl中只有一个string类型的变量,所以当要操作数字进行运算的时候,tcl提供了incr和expr两个操作数。 incr的基本用法为: incr variable integer(variable必须为数字...

The returned environment handle is bound to a Tcl command of the form envN, where N is an integer starting at 0 (for example, env0 and env1). The env_handle open open an environment handle. The path is the directory in which the database files reside. This directory must already ...
• Choices between arguments are represented by pipes, for example: priority low|normal|high Note For all EEM Tcl command extensions, if there is an error, the returned Tcl result string contains the error information. Note Arguments for which no numeric range is specified take an integer ...
