软件过程管理里面有个sloc是什么？

软件过程管理里面有个sloc是什么:

SLOC(single line of code),代码行LOC的基本单位之一。

附：代码行相关知识

代码行(line of code)指所有的可执行的源代码行数，包括可交付的工作控制语言(JCL：job control language)语句、数据定义、数据类型声明、等价声明、输入/输出格式声明等。一代码行(1LOC)的价值和人月均代码行数可以体现一个软件组织的生产能力。组织可以根据对历史项目的审计来核算组织的单行代码价值。代码行LOC常用于源代码的规模估算，常使用的单位有：SLOC(single line of code)、KLOC(thousand lines of code)、LLOC(logical line of code)、PLOC(physical line of code)、NCLOC (non-commented line of code)、DSI(delivered source instruction)
