使用IDA導出map文件時，在不需要Label信息的情況下，不要選中"dummy names"選項，否則在Ollydbg中使用LoadMapEx(by forever)加載時，會將OD的註釋替換掉
對於 dummy names，IDA幫助中的解釋是這樣：
Dummy names are automatically generated by IDA. They are used to denote subroutines, program locations and data.
Dummy names have various prefixes depending on the item type and value:
sub_ instruction, subroutine start
locret_ 'return' instruction
loc_ instruction
off_ data, contains offset value
seg_ data, contains segment address value
asc_ data, ascii string
byte_ data, byte (or array of bytes)
word_ data, 16-bit (or array of words)
dword_ data, 32-bit (or array of dwords)
qword_ data, 64-bit (or array of qwords)
flt_ floating point data, 32-bit (or array of floats)
dbl_ floating point data, 64-bit (or array of doubles)
tbyte_ floating point data, 80-bit (or array of tbytes)
stru_ structure (or array of structures)
algn_ alignment directive
unk_ unexplored byte
