Sambal programming language:

Code:

LET b= 20
b /= 2
MSGBOX b
b +=30
b -=1
MSGBOX b
LET c=40
c*= 22
MSGBOX c

Using the Sambal compiler(written in C#) will generate a Windows EXE.

This simple Win32 compiler is not using FASM as back-end compiler directly, but I reverse-engineer the PE file generated by FASM to study how to output the binary executable.

As such, the linker version is not the same with that of FASM, but dosHeader and importTable are kept intact as what have been produced by FASMW.

Admin and mods are welcome to move this topic of discussion to elsewhere if my toy programming language is irrelevant. Thanks!

And how compile example1.txt ?
Show example.

And what about floats nums ?
For example: a = 1.2*2+2.4

Thanks for your interest. Just drag the source text file and drop it on icon of Sambal.exe or use command-line:

Code:

Sambal example1.txt

Floating numbers is not supported as I am beginner to compiler scene and slow in improving the compiler. In future, iteration construct and conditional statement will be supported.

For my parser, you have to code it in something like this:

Code:

LET a=1
a *= 2
a+=3

It is far from perfect.
