Ignoring 20 characters

[Guest_imported]

I have the following txt file:

S San Diego 4 20:30

------------------------
**San Diego can be the name of any city not more than 20 characters long***
How do I make the read in statment to ignore what comes after S. (Means maxiumum 20 characters and then continue reading).


Thanks GUYS

Well if the City Name is padded with spaces to a max of 20 chars simply move the file pointer forward 20 bytes, then start reading. However, if the City name is unknown you will have to read it a byte at a time until you come to say a space then read the next byte. Check this byte to see if it's a char if it is you (in theroy) could assume thats it's a continuation of a City name, like San Diego. On the other hand if it's number you can (in theory) assume that you are now at the position from where you want to read from and continue your processing.
