ASM tools

[William Beech]

Guys,

Do we have a tool for Intel 8080/85 assembler to show label definitions
and label uses?

Thanks!

Bill

I seem to remember an XREF switch somewhere...

Could be bewildered...

Regards

Sid

All
Intel's ASM80 supports the XREF switch (and the NOXREF option).
On ISIS this automatically invokes ASXREF, on my C port this is built in and also supports long symbols. The cross reference is appended to the listing file.

PLM80 supports to XREF options
1) simple XREF shows XREFs in a file, it also shows additional type information for the symbols.
2) IXREF emits a cross reference file (.IXI) to disk. The IXREF tool can then be used with multiple IXI files to create a cross reference over multiple files.
The ISIS version uses ISIS.DIR to allow wildcard filenames. If my version of the Thames emulator is used it will auto generate ISIS.DIR to support this. It also generates a synthetic ISIS.LAB
Pre PLM80 v4, the IXI file included disk volume names, PLM v4 replaced with blanks, possibly because as disks got bigger it was no longer particularly useful.
My C port of PLM-80 uses the previous disk volume space to allow longer filenames to be captured. My C port of IXREF displays the longer file names, but if ISIS IXREF is used
It shows part of the filename in the disk volume column. Note very long filenames are truncated.

Mark,

The "$ XREF" in the source did the trick.  Thanks!

This makes finding unused code segments in the ROM images much easier!
