	Another issue for assembler programmers in general is the list of so-called [[monitor calls]] (MON). The MON instruction is equivalent to the INT instruction found in [[Wikipedia:List of Intel microprocessors\|Intel CPUs]]. However, while they originally had a nice set of functions to write to a file, read from a file, etc; it quickly devolved into an ad-hoc set of functions. An example being a function originally designed to output 8 bytes stored in 4 of the registers (A, D, T and X). Soon someone, having the bytes in some other registers, made a new function to output from those registers. This left the programmer with a veritable forest of output functions all doing almost the same thing. In the latter days of [[SINTRAN III]] the problem then was to find available codes for these system calls as all 256 of them had already been taken by several such near identical functions. Thus, the extended multi-function monitor calls entered the scene where one monitor call could do a number of functions with a function code specified in a register designating which of its subroutines would be executed.
