男友报备:关于Debug

Debug 英文词，程序查错的意思。bug原意是小虫，例如跳蚤，虱子，苍蝇等，Debug就是找小虫，消灭它。

Debug有很多方法。

自己手工查错，例如加入许多打印语句，进行执行线路跟踪，找到出错地点，假设输入变量值的范围变化，看哪里溢出。也叫Debug。

VC++里有VC++的Debug，执行线路跟踪，变量变化跟踪，内存变化跟踪。在Visual Studio控制下，Build->Start Debug下有各种查错方法可用。

DOS里有Debug, 在DOS窗打命令Debug启动Debug，拍入问号，你可以得到详细的Debug用法：
Runs Debug, a program testing and editing tool.
DEBUG [[drive:][path]filename [testfile-parameters]]
[drive:][path]filename Specifies the file you want to test.
testfile-parameters Specifies command-line information required by
the file you want to test.
assemble A [address]
compare C range address
dump D [range]
enter E address [list]
fill F range list
go G [=address] [addresses]
hex H value1 value2
input I port
load L [address] [drive] [firstsector] [number]
move M range address
name N [pathname] [arglist]
output O port byte
proceed P [=address] [number]
quit Q
register R [register]
search S range list
trace T [=address] [value]
unassemble U [range]
write W [address] [drive] [firstsector] [number]
allocate expanded memory XA [#pages]
deallocate expanded memory XD [handle]
map expanded memory pages XM [Lpage] [Ppage] [handle]
display expanded memory status XS

不同机种有不同的debug.

“详细的解释”要看是那个Debug软件，自己查书或Debug自带的帮助文件或说明。

软件的调试。
