70s textbooks

Why are old textbooks and manuals so boring? I'm not asking for w(p)gtr bullshite, but these books are written in such a matter-of-fact way it makes them more difficult to follow.

get FileName |c:[T:@4.utf8 L:@4.ul D:@L.y? @Xs] [[T D] @Xs,r]

C/C++ (don't need to understand a computer to do low skilled programming work):

#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
#include <string.h>

typedef struct chunk {
  uint8_t Tag[5];
  uint32_t Len;

  int I, L;
  uint8_t *D, *P, *E;
  chunk *C=0, *T, *N;
  FILE *F = fopen(FileName, "r");
  fseek(F, 0, SEEK_END);
  L = ftell(F);
  D = P = (uint8_t *)malloc(L);
  E = P+L;
  fseek(F, 0, SEEK_SET);
  fread(D, 1, L, F);
  fclose(F);

    T = (chunk *)malloc(sizeof(chunk));
    memcpy(T->Tag, P, 4);
