is-dos file operations

Hello, dear all! People! How to read files in IS-DOS not block by block, but byte by byte? There seems to be a function rpart(#29), however, nothing works with it, and with block (rifle(#2b)) everything is ok. Maybe there are some parameters needed? Throw a piece of listing into the echo, please... Bye, √a└e┌┐┼!┌┐ P!┌┬┐e┌┐0√ -+- SMM version 1.08
