BUG: F6103 Reading "0." into COMPLEX NumberLast reviewed: December 10, 1995Article ID: Q106730 |
The information in this article applies to:
SYMPTOMSAttempting to READ "0." into a COMPLEX variable produces the following error:
run-time error F6103: READ(file_name) - invalid realThis error occurs with standard- or list-directed formats on internal and external files. Inputs of 0, 0.0, and .0 as well as all other numbers ending in a decimal point can be correctly read into COMPLEX variables.
RESOLUTIONInput 0 (zero) rather than 0. when reading complex values using formatted I/O.
STATUSMicrosoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
MORE INFORMATIONThe following program demonstrates that with PowerStation, imputing 0, 0.0, or 1. does not produce any errors, but imputing 0. produces the F6103 invalid real error. The output when compiled with PowerStation is:
In: 1.,1. Out: (1.000000,1.000000), error #: 0 In: 1.,0. Out: (1.000000,1.000000), error #: 6103 In: 0.,1. Out: (1.000000,1.000000), error #: 6103 In: 0.0,0.0 Out: (0.000000E+00,0.000000E+00), error #: 0 In: 0,0 Out: (0.000000E+00,0.000000E+00), error #: 0 Sample Code #1Compile options: none
