Ok ....it goes like this....
Syntax: $fopen("file_name","file_open_mode"); different fopen modes "r" or "rb" Open for reading "w" or "wb" Truncate to zero length or create for writing "a" or "ab" Append (open for writing at end of file) "r+", "r+b", or "rb+" Open for update (reading and writing) "w+", "w+b", or "wb+" Truncate or create for update "a+", "a+b", or "ab+" Append; Open or create for update at end-of-file eg: integer op_file; op_file = $fopen("DATA_OUTPUT_FILE.txt","w"); $fwrite(op_file,"%h\n",FILE_DATA); //FILE_DATA represents the DATA to be written into the file $fclose(op_file); //to release the memory allocated, If the opened files are not closed properly u may end up with wrong results. This shuld be done only after completely writing required data into the output file. Hope this helps u....feel free to contact Regards PKPM- Mark as New
