SUMMARY
MASM returns an A2041 error (String or Text literal too long) when passing to a MACRO a set of parameters whose total length is greater than 255 bytes. The inidvidual parameters may be shorter than the stated 255 byte maximum, but the MACRO expansion treats the entire parameter list as a single string (text literal).



MORE INFORMATION
This behavior is by design, though it is not currently documented as such. The following code demonstrates this behavior: .486  .486   .MODEL FLAT .CODE

menu_list   macro   item1,item2,item3,item4,item5,item6,item7 endm

menu_list      <'ACTION1','ACTION1','ACTION1','ACTION1'>,\ <'ACTION2','ACTION2','ACTION2','ACTION2'>,\ <'ACTION3','ACTION3','ACTION3','ACTION3'>,\ <'ACTION4','ACTION4','ACTION4','ACTION4'>,\ <'ACTION5','ACTION5','ACTION5','ACTION5'>,\ <'ACTION6','ACTION6','ACTION6','ACTION6'>,\ <'ACTION7','ACTION7','ACTION7','ACTION7'> end This is the message MASM returns upon compiling this sample:
