Hi,
The following C code, at present does the following :-
Takes the Output file name from character 1 of the input filename (ALLSMFAS.ref) and creates a new file (A.brt) as follows :-
ALLSMFAS.ref
AD,B,0424,0415,89375,,A,2,,80,,
AD,B,0424,0417,89375,,A,1,,82,,
AD,B,0416,0410,89375,,B,2,,-7,2,

For each change in the value at column 1 of input file, a new output file should be created, as follows :-
ALLSMFAS.ref
AD,B,0424,0415,89375,,A,2,,80,,
AD,B,0424,0417,89375,,A,1,,82,,

and so on..the following are the output files.
AD.brt
B0424041589375 B0424041789375 B0416041089375BN.brt
B0135009465625 B0338033765824 B0334033965824CA.brt

B1783157448231 B1783157648231 B1783157848231and so on ….
The logic for taking the output filename name from character 1 of the input filename is as below :-
1234567// Take the brt file name from character 1 of the input filename.<br /><br />memcpy(this_td,<br />wfd.cFileName,<br />1);<br />this_td[2] = 0;<br />I think I have to change at this place so that the code reads each value of column 1 of my input file (ALLSMFAS.ref) and
create Output file with name as the value at the column 1 of the input file. For each change in the value at column 1 of
input file, a new output file is created. I am unable to proceed further to implement this.Request you, if you could please help me on this.

Marconi.Heres some code that does what you want ( maybe you can splice this into your program ):
