Save valuable programming time with this collection of more than 40 useful subroutines. Each routine has been documented, tested and debugged, and is ready to use immediately.

Z80 Assembly Language Subroutines provides you with 

• General Z80 programming methods (including a quick summary for experienced programmers).
• Routines for array manipulation, arithmetic, bit manipulation, code conversion, string processing, input/outputs and interrupts.
• A discussion of common Z80 assembly language programming errors, as well as the strengths and weaknesses of the Z80 instruction set.
• Directions for implementing additional instructions and addressing modes.

With these subroutines, you can

• Run a specific routine.
• Speed up a program written in a high-level language such as BASIC, Pascel, or Fortran.
• Assist in programming an I/O driver, a diagnostic, a utility, or a systems program.
• Debug, maintain, or revise an existing program.
