第十讲上机操作一个BASIC程序编好以后,如何进行上机操作呢?下面就CROMEMCOZ—80机进行介绍。一、调出BASIC解释程序当打开机器,装上磁盘以后,机器就自动地将操作系统调入内存,在屏幕上显示A>提示符。但是BASIC语言程序必须在BASIC解释程序控制下工作,所以在输入BASIC语言程序以前,还必须调入BASIC解释程序。其方法为键入BASIC〈CR〉(这里的〈CR〉是回车,在机器上是按RETURN键——下同)。等待机器显示屏幕上出现>>提示符,表示机器已进入BASIC控制的状态,就可以将程序逐句键入。二、程序的输入在>>提示符出现以后,先输(键)入标号,然后键入本行的各语句,一行的全部内容键完,必须按一下回车,此时,在下一行又出现>>提示符,即可键入下一行的语句内容。当整个程序键入完毕,可以用LIST命令来阅
The tenth talk about the operation of a BASIC program compiled, how to operate on the machine? The following describes the CROMEMCOZ-80 machine. First, call out the BASIC interpreter When the machine is turned on and the disk is mounted, the machine automatically brings the operating system into memory and displays the A> prompt on the screen. However, BASIC language programs must work under the control of the BASIC interpreter. Therefore, BASIC interpreters must be called before BASIC language programs are input. The method is to type BASIC (where is a carriage return and the machine presses RETURN - the same below). Wait for the >> prompt to appear on the display screen of the machine, indicating that the machine has entered the state of BASIC control and you can type the program step by step. Second, the program’s input After the>> prompt appears, first enter (key) into the label, and then type the statement of the line, the entire content of a line finished, must press Enter, this time, in the next line appears again> >Prompt, you can type the contents of the statement on the next line. When the entire program is typed in, you can use the LIST command to read
