One of the facilities that the use of macros provides is the formation of libraries, which are sets of macros which can be included in a program from a different file. The formation of these libraries is very simple; we only have to write a
file with all the macros which will be needed and save it as a text file. To call these macros it is only essential to use the following instruction contains Name of the File, on the division of our program where we would generally
write the macros; this is, at the starting of our program, before the assertion of the memory model.
The macros file was saved as MACROS.TXT, the instruction Include would be used the following method:
Beginning of the program take in MACROS.TXTMODEL SMALL DATA .The data go away CODE
Beginning: The code of the program is placed in STACK the stack is defined End beginning our program ends
