Hello,

I am having some difficulties using Pinnacle 52 projects and modules. I have attached two simple files which illustrate my problem (at bottom).

I am using Pinnacle 52 1.130 on Windows XP professional.

As you can see I have two source files in my project called FILE1.ASM (Main program) and FILE2.ASM (Library containing two modules, SUBB1(Containing two subroutines ROUTINE and PRIVATE) and SUBB2(Containing one subroutine PRIVATE). As you can see in the main program I have declared ROUTINE and PRIVATE as EXTERNAL and within SUBB1 I have declared ROUTINE as PUBLIC and within SUBB2 I have declared PRIVATE as PUBLIC.

As you can see the SUBB1 module contains a subroutine called PRIVATE but as this module does not declare PRIVATE as a PUBLIC symbol it should not be “visible” to other modules? But this does not seem to be the case. As you can see from the Code Window (Disassembly) the supposedly “invisible” PRIVATE subroutine within the SUBB1 module is being confused with the intended PUBLIC subroutine PRIVATE within the SUBB2 module.

Also notice that at Addr 003F the program is trying to call a subroutine at 0048 which does not contain any Opcode but is where the PUBLIC subroutine PRIVATE should be?

Another worry for me is that removing the two lines within FILE2 declaring ROUTINE and PRIVATE as PUBLIC does not induce any errors and has no effect on the code produced? According to the Pinnacle Help this should not be possible?

Can anyone confirm if what I have done is correct? Am I using the wrong syntax somewhere? If anyone running Pinnacle 52 tries to build these files do they get the same results? I am convinced that I must be doing something obvious wrong but I have been through all the help files etc. and can not see anything? Could anyone who uses Pinnacle provide a working example illustrating the correct use of modules?

Any help would be greatly appreciated,

Best regards,

EI.
