Title: Information processor
Inventor: SAKURAGI YUTAKA
IPC: G06F9/45
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To provide an information processor which performs translation by a compiler in a method different from the declaration of a user when processing is performed preferably in the different method from the declaration of the user by making the compiler flexibly judge the contents of a source program. SOLUTION: The source program 11 that the user has made is inputted to the information processor 2 and held in a source program hold part 21. Line number information inputted by the user is held in a line number information hold part 23. A syntax analytic part 25 generates internal numbers in the source program 11 when a line number information decision part 29 decides that the no line number information contains no line number, and sets them in the source program hold part 21. At this time, the syntax analytic part 25 performs translation by using the internal line numbers and when the information has line numbers, translation is carried out by using the line numbers that the user has given. Thus, the compiler automatically decides whether or not the source program has the line numbers, and gives the internal lines numbers to conduct a syntax analysis.  Consequently, a case wherein an error place can not be found because of no line number is eliminated to improve the efficiency of program development.

Filed: 1994-09-26
Abstract: PURPOSE: To prevent a brake lamp from lighting and to eliminate the delay of releasing the brake when an HSA-valve, which has held the brake in a work ing state, is turned off. CONSTITUTION: When HSA-valves 20, 21 are turned OFF from ON by an HSAECU32, an ON-signal is outputted to the HSA-valves 20, 21, and simultaneously control signals over ABS-modulators 5, 11, 12 are outputted to an HSA- modulator controlling means 22a as well. On receiving this control signal, the HSA-modulator controlling means 22a sets all the ABS-modulators 5, 11, 12 at an ABS-decompression mode for a certain period of time. With this, compressed air within brake actuators 6, 13, 14 is discharged from the ABS- modulators 5, 11, 12 into the atmosphere, not being discharged from a brake valve 16. As a result, pressure switches 35, 36 do not detect the pressure any more, and consequently a brake lamp 38 does not light and the brake is released quickly.
