Hi
"Error 52, Invalid character in field"
anyone seen this error?
It occurs when trying to read a data file:

what's problem?

My initial guess would be that the format of your data file does not meet the format declaration of the variables d, u or ff.

Yeah you should put a format statement otherwise how is it going to know what to look for? Lets say you are reading 3 reals that are floating point numbers 12 spaces wide with 9 decimal places and are separated by 3 spaces you would use:

read(14,100) d(i),u(i),ff(i)
100 format(F12.9,3x,F12.9,3x,F12.9)
