MPLAB (splitting .asm files)

[shaun_c_m]

one of my recent has reached about 3000 lines including comments and it is a right sod to try to keep track of where everything is when its in one huge list.

is it possible to put different subsections/subroutines into different files whilst still being able to assemble and simulate it?

how would i go about splitting 1 big asm file into smaller manageable chunks?


thanks

Did you tried #include <file name>?
I used it before for big project in assembly language.

i have found the include directive, but its doing something annoying

let me explain with an example

;


main code    ;relocateable code section

Main:

	goto testsubroutine   ;this is in another .asm file


;*******************************************************************

theend
	goto	$                      ;go no further than here

;End of program

	#include <test.asm>           ;include file, put it out of the way


		END

[second file]

test code            ;another section of code in a different file

testsubroutine     ; the first routine called

	nop
	nop
	goto     theend      ; i am trying to branch to a label somewhere in the first file

	end

in this example the "goto theend" throws up the 'object not previously defined' error.

although it isnt defined in this second file, it is defined in the first.

i seem unable to goto a subroutine that is not in the second file.

im confused at how this all works.

you cannot use a name before the name is declared.

So try to declare the name before it is used.

ive finally figured it out!!!!

i needed to add the line

global theend

into the first file. it seems to work happily then

you were right that i hadnt defined it in the second file, but i wanted it to go to a place in the first file. telling the assembler this bit of info seems to remody the problem. YAY!!!

Glad to hear that.

how can we put #include <whatever.asm> or #include <test.bas> in BASIC language?
