PURPOSE:To output a more definite error message and to accurately indicate a correction portion by suppressing the chain error processing caused by a description error to a minimum when a form language source in which the description error is incorporated is analyzed. CONSTITUTION:By dividing a syntax analysis processing into a syntax form decision processing part 4 and a validity decision processing part 5 and dividing the error processing generated at each part, the mutual interference of the errors on the both parts is canceled. A syntax form decision processing part 4 performs a processing deciding the form of the format generated due to the description omission of a character string, in particular. The validity decision processing part 5 performs a processing deciding the validity for every character string of a spelling mistake. Thus, the chain error processing generated due to the description error is possible to be evaded. When a large quantity of form languages are analyzed in particular, the correction portion of the form language source where a description error is difficult to be found can be accurately indicated. |
