columns. 181 182 The first column is CPU-id, the second is PID, third is the time since boot in 183 microseconds since the previous action. The fourth and fifth columns 184 represent the action happening. The Tcl command or procedure name is prefixed 185 by an indicator reprenting what is happening. These may be -> (procedure 186 entry), <- (procedure return), > (command entry), or < (command return). 187 188 As each action is taken, the fourth and fifth columns are indented by 2 spaces. 189 This shows which procedure or command is calling which. 190 191 If the output looks shuffled, check the CPU "C" and "TIME" columns, and 192 post sort based on TIME if necessary. 193 194 See Notes/ALLflow_notes.txt for important notes about reading flow outputs. 195 196
