汇编LOG怎么看

一汇编中常见的数据类型

C = 字符
H = 半字
F = 全字
D = 双字
X = 十六进制数
B = 二进制数
P = 压缩十进制数
Z = 非压缩十进制数

AREA DS CL4
AREA2 DS 4CL1

CL4是一个很常见的定义
类似的还有PL5,XL6

第一个定义保留4 个字节的区域，并将该区域的首地址赋予AREA，该区域
的长度为4 字节

；第二个定义同样保留了4 个字节的区域，并将该区域的首地址赋予AREA2，
但该区域的长度为1 字节。

二一个汇编大致的LOG

The external symbol dictionary shows a named common statement. The named common section is defined in statement 257.B 
Statement 38: Save the status of the PRINT statement.
Statement 39: Modify the print options to DATA and NOGEN.Statement 40: Macro call; the expansion (statements 41 and 44) is not printed.Statement 45: All 28 bytes of data are displayed to the two-operand DC.Statement 46: Restore earlier status of PRINT.Statement 48: This statement is not printed. It is a nested macro call. The MCALL operand of the PRINT instruction or the PCONTROL assembler option control the printing of nested macro calls.Statements 51: The generated output of the macro WTO is shown, but only two bytes of data are shown.
