Labels

 

A label is a sequence of no more than four digits, that is, a numeral between 0 and 9999. Leading zeros are not significant. Identifiers can also function as labels.

Labels are used in goto statements. For more information about goto statements and labels, see Goto statements.

译文

 

标号

 

标号是一个不能超过4为数字的序列(09999之间的数字)。标号中首位数字为0是没有意义的,如标号 0010 10 等同。标识符也具有与标号相同的功能,也就是说,标号可以是数字,也可以是标识符,但数字标号的定义范围只能是09999之间(含09999)。

标号用于goto语句,相关的更多信息见Goto语句
