ROMJ User Manual in HTML
 ROMJ Source Code ZIP   romj.asm and macro.src, source to make ROMJ using ML-ASM.
 ROMJ in HEX format All ROMJ versions-ready to burn.
 LODNGO  A BASIC program to load the hexload portion of ROMJ, for my 3X1 board, and load the rest of ROMJ.
                             Caution, this requires a board which can load a HEX program, and be reconfigured to reset,  and run
                             a Command Expansion Program! See the Basic-52 manual for requirements.
 MCS-51 BASIC Manual Intel's manual zipped.
 HEX Load and Prog  Load an Intel Hex file, with relocation feature, and program an EPROM.
HEX Load  Load an Intel Hex file, with relocation feature.
 MACRO.SRC  Macros I wrote to make the expansion easier to write. I even made a macro for a CASE test.
                          Note: this is required, as well as ML-ASM, to assemble ROMJ.
ROMJ Source in text format if you just want to see it...
 ROMJ XREF   A cross-reference listing of the ROMJ ASM program, for those who want to modify it,
                                   which lists the variable names and labels and the line numbers they are used on.
 BASIC-52 XREF   A cross reference of the CMOS BASIC-52 source. No linking required.
 FP-52 XREF          A cross reference of the FP source for BASIC-52. No linking required.
 ASMXREF.CBL   A quick hack in COBOL to produce  a ML-ASM cross reference listing. This version
                                          only processes the labels of certain ASM Directives. It doesn't process the operands
                                          of EQU BIT MACRO DB DW, and ignores DATA CODE RET NOP RETI.
                                         If you want to run it, you'll need Personal COBOL from Microfocus. Microfocus has
                                         three versions that are available. Students can get them at the college bookstore, or
                                          from their website. Versions are also available for non-students, but at a higher cost.
                                         Why not do it in C? I gave up after a week of hacking at it, the COBOL program  took
                                          two hours to write and debug, for the first version. strtok in C/C++ is much harder to
                                          work with than string/unstring in COBOL, and internal sorts are standard in COBOL.

Why ROMJ?

Well, Micromint had used A,B,C,D? and I wanted something new, so I started at F.
J is the last version which I finished about 10 years after the first version. Much of the earlier
code is very compact, and labels/comments may be brief-I was developing it on a BCC-52 from
Micromint using their ROMA&B, ASM and editor, and which only had 32K for workspace.
Later updates were on the PC using ML-ASM.

If you look at the source, you will see about 5 or 6 different styles of coding, and it may be good,
bad, or "it works!". I often tried adding too many features to the code, and then deleted the extra, or
I just had a bad day. Anyway, if you are developing BASIC or BASIC and ASM for the
8051 family, it may be useful, or provide some examples of ASM coding. The macro.src has a few
constructs which make life easier for ASM coding.
