AH, that's what those ifdefs I see are. Thanks for the explanation, finally puts it together for me.

Hey Scot,
Code:<MvCOMMENT>-SDS-- </MvCOMMENT> <MvIFDEF NAME="SOUTHBOUND"> Some specific code here </MvIFDEF>
Code:mvc -D SOUTHBOUND -o ids_tools.mvc myproj.mv
Code:mvc -D SOUTHBOUND -D SHOWJSONVARS -o ids_tools.mvc myproj.mv
Code:<MvINCLUDE FILE="file1.mv"> <MvINCLUDE FILE="schedtasks.mv"> <MvINCLUDE FILE="core.mv"> <MvINCLUDE FILE="required.mv">
I haven't organized any project this way -- yet, but as you suggest, I will be considering using MvIFDEF in the project file in the future.
It's all very flexible. Flexibility is needed when I have many old projects that never had any organization and everything was a "make-from" based project. Also, IMO, there would be a lot of work with code and files and adjusting a MAKE File if I decided to try and use something that again. IFDEF and INCLUDES have made it easier to resurrect much of that older code and there is less re-inventing of the wheel. Still, are there better ways? Likely...

Scott, will you give me an example of a scenario in which you are using the -D flag to compile different code for different clients? Is it kind of like using the MvINCLUDE tag but having different sets of include files based on what you need for the particular integration?

Initially, it would be for debugging code. But, as I do more integration services, the module portion sometimes needs targeted code that is specific to the client. Instead of having multiple versions of the module, I use it to keep everything in one set of source code. I needed multiple symbols to be able to compile debug and/or targeted versions. I can then control what is compiled via batch files. For me, it's more straightforward than creating branches in a version control system for instance because it's usually not "core" functions that need to be included or not included in the compiled module.

Are you asking why as a use case or curiosity?
Thanks. Yes, I just realized, if you leave out the -D before the second symbol the compiler is looking for a folder that doesn't exist.

Why are you defining so many tokens in your program? The correct syntax would be mvc -D token1 -D token2 ... file.mv

for what its worth, none of my batch files I use for compiling have brackets around anything.

compiler question
I am not finding the compiler manual in the docs. Seems like it should be simple, but it really isn't explicit IMO.
I find I am using -D more and more.
Code:mvc -D SYMBOL[-D ANOTHER_SYMBOL] source.mv
Is it:
Code:-D sympbol1 symbol2
Code:-D sympbol1 -D symbol2
