You can program a controller in assembly, but most people will advise you to write the program with a c-compiler. This makes it's more easier to use third party c-source and you can port it later to another processor. There is a free compiler available (cosmic compiler) if you have a small program (up to 4kbyte).
I must admit that I also started with assembly. It proved to be usefull for writing some time critical routines later. It's not much different from writing assembly programs for the AVR or PIC processors.
You can download ST7VD to get started with assembly. More information about the assembly instructions can be found in the help menu. You can also download a datasheet of a part to have a look at the assembly instructions. The ST7VD software can also be used with compiling C-source. Have a look on

for the free st7 compiler.

Mark
