Small tool in ML64 complete with source.

[hutch--]

The tools in the MASM32 SDK have an item called "tview.exe". The attached file is a 64 bit version with the same task, a bare edit window that will load a file on the command line. It is a results viewer that has 2 keys, F1 to copy the results and the ESC key to close it. It is a little bigger than the 32 bit version but it has a manifest, version control block and the first monochrome icon I have ever made and it comes in at 8.5k (8704 bytes).

So far I am reasonably pleased with the prologue/epilogue code and the function call automation with "invoke". It can be used close enough to how its was used in Win32 code with only minor differences in notation, the need for "\" for split lines and the more obvious difference, no prototypes or error checking.

If you have got the later build environment that I posted recently, this tiny app should build OK.

Don't get too dazzled by always using a 64-bit register, plenty of parameters can be passed via ECX et al if it's a dword.

All those extra bytes add up...

The invoke style macro does it automatically, IE puts the right size data in the right place. I know what you are after but I see size optimisation through register size as pointless as the savings are small. The target I am after with Win64 is /LARGEADDRESSAWARE type applications where Win64 has a large advantage. For size optimisation Win32 does it better.

My Windows 10 doesn't like your icon. Started off normal, now has changed to two different icons (funny, the current icon is for "Windows 10 Upgrade Assistant").
Probably an icon cache problem - you would think that they corrected this, since it occurred in WINDOWS 98.

Anyway, leave ML64 to us purist fossils, use your newfangled (h)jwasm  :P
Invoke? Pah!

But we ARE purists using a MACRO assembler. There are still a few minor optimisations to do with the "invoke" style code, test if the value is zero and use XOR or SUB and in the first 4 args, if a reg is copied onto itself it can be left out. At least there is no native invoke, the macro is called "procedure_call" and invoke is only a wrapper for it. The icon works OK on my Win 10 Professional but there are other PHUKUPS with the icons on my start menu, my TightVNC is getting the Axialis Icon Workshop icon instead.
