However, C language programming is much easier to obtain skilled people in, so most if not all new development is done in C. Since z / TPF allows assembler programs to be repackaged into 1 logical file, critical legacy applications can be maintained and actually improve efficiency-the cost of entering one of these programs will now come at the initial enter when the entire program is fetched into core and logical flow through the program is accomplished via simple branch instructions, instead of a dozen or so IBM instructions previously needed to perform what is known as ' core resident enter / back '.

Since terminals were connected through various types of front-end processors ( as per common IBM timesharing practice both then and now ), and could therefore function without CPU attention for a considerable amount of time, MUSIC used variable-length time slices, which could, on compute-bound processing, reach a maximum of several seconds per time slice ; conversely, if a user filled the output buffer or reached a conversational read, the timeslice would end immediately.
