L #First_byte_to_write // Offset of the first Byte to write
SLD 3 // build the Pointer format
T LD [AR1,P#6.0]
L B#16#4 // area code global data
T LB [AR1,P#6.0]
SET // indicate of global pointer format
S L [AR1,P#6.7]
========================================================
上段程序不明白为什么两次进行数据区6.0进行定义,末尾为什么置位6.7
请各位给解释下好吗?谢谢
