Multiple file assembly support

In assembly language, there are some directives related to multiple file assembly like : [`include`](https://docs.microsoft.com/cpp/assembler/masm/include-masm)
[`includelib`](https://docs.microsoft.com/cpp/assembler/masm/include-masm)

For example, `include test.asm` We need to find file named `test.asm` in the current folder. Should we find other files like the ones in PARH?
