"Invoke" 64-bit

[Greg_M]

Hi, I'm new to MASM and the MASM forums. The "INVOKE" documentation states "(32-bit MASM Only) ...".
https://learn.microsoft.com/en-us/cpp/assembler/masm/invoke?view=msvc-170

I see code examples of INVOKE here, so I'm seeking understanding.

Update: Apparently, MASM INVOKE isn't applicable to 64-bit MASM (ml64.exe), but alternatives, such as macros, are.

Hi Greg,

Microsoft crippled ML64, so invoke, .if .else .endif, .Repeat ... .Until and others are no longer built-in. Therefore you basically have three options:
1. Bare metal: no macros (for Real Men^TM)
2. The macros developed by Hutch and Vasily in the Masm64 package
3. UAsm or JWasm

Note that Vasily's invoke does not check for the number and/or type of parameters passed. JBasic's jinvoke does, but it's work in progress.

Welcome to the forum

OK, thanks very much, including for the well-stated, and thorough number of, options!
