59 * The space command forces an immediate update. Sometimes, on loaded
60 * systems, this update will take a significant period of time (because all
61 * the output is buffered). So, if the short-term load average is above
62 * "LoadMax", then top will put the cursor home immediately after the space
63 * is pressed before the next update is attempted. This serves as a visual
64 * acknowledgement of the command.
69 * "Nominal_TOPN" is used as the default TOPN when
70 * the output is a dumb terminal. If we didn't do this, then
72 * process in the system when running top on a dumb terminal (or redirected
73 * to a file). Note that Nominal_TOPN is a default: it can still be
74 * overridden on the command line, even with the value "infinity".

79 * If the local system's getpwnam interface uses random access to retrieve
80 * a record (i.e.: 4.3 systems, Sun "yellow pages"), then defining
81 * RANDOM_PW will take advantage of that fact.
