TRON是BASIC语言中的一条调试指令,其为TRace ON的缩写,主要用于调试带行号BASIC的GOTO和GOSUB语句。在文本模式环境中,例如TRS-80,MS-DOS/IBM PC-DOS,执行这条指令允许进程在屏幕上显示当前执行指令的行号。在窗口环境中,若执行了TRON指令,则会出现一个显示当前指令行号的窗口。其对应指令为TROFF,为TRace OFF的缩写,用于关闭命令追踪。

TRON command TRON指令

(重定向自TROFF)

TRON is a debugging command in old dialects of the BASIC programming language. It is an abbreviation of TRace ON. It was used primarily for debugging line-numbered BASIC GOTO and GOSUB statements. In text-mode environments such as the TRS-80 or DOS, it would print the current line number which was being executed, on-screen. In a windowed environment, when the TRON command had been executed, a window would indicate the line number being executed at that instant. This command's opposite is TROFF, or TRace OFF, used to turn off command tracing.
