Hello All,

I an not new to the MCS51 world but it has been a few years since I last developed on one.

I am working on a project that is based on a 87C32. I am using the original Intel assembler/linker that is dated around 1993. I need to use the upper 128 bytes of the internal RAM for data storage and I am having a tough time configuring the assembler/linker to allow this. I have done this before but it was about 6 years ago.

I understand that any RAM located above 07Fh must be accessed indirectely. The problem I am having is just a matter of declaring the variables correctly so the assembler won't spit out syntax errors and the linker will place the data in the correct location. I believe part of the problem is that I want to have the direct and indirect data spaces immediately follow each other. In other words the direct address space ends at 060h and I need the indirect to start at 061h.

Anyone have any examples on how they set up thier data space in assembly? Any good websites that describe how to accomplish this?

Thanks,
