In this post, Raymond Chen talks about the technique of jumping into the middle of an 8080 instruction that is found in Microsoft BASIC disassembled source code. Since Z80 is compatible with 8080, does MSX-BASIC also feature this technique?

Jumping into the middle of an instruction is not as strange as it sounds

Yes, it is used a lot. Take for example the floating point module, or even beter the main basic module, look for "trick"
