Hi all
I am trying to compile the following statements using CPP.
IF ( denominator > 0 ) THEN
IF ( mod( numerator, denominator ) /= 0 ) THEN
IF ( numerator > 0 ) THEN
WRITE(frac_str,FMT="('+',I2.2,'/',I2.2)") abs(numerator), denominator
ELSE ! numerator < 0
WRITE(frac_str,FMT="('-',I2.2,'/',I2.2)") abs(numerator), denominator
ENDIF
ELSE ! includes numerator == 0 case
frac_str = ''
ENDIF
ELSE ! no-fraction case
frac_str = ''
ENDIF
However the error is here

Does anyone know how to make cpp can compile empty character constant?
Thanks in advance
Bruce
Thank you
