It really depends on what is in those files.
From the documentation page linked by an earlier reply you might be lucky and they are just simple tab delimited files.
-c Performs the operation using a character data type. This option does not prompt for each field; it uses char as the storage type, without prefixes and with \t (tab character) as the field separator and \r\n (newline character) as the row terminator. -c is not compatible with -w.
LOOK at the file and see what you have.
Check to see if they are text files with lines by looking at the first 5 lines.
filename BCP 'myfilename.bcp';
data _null_;
infile bcp obs=5;
input;
list;
run;
Or look at them a binary files. To check the first 500 bytes you could use:
data _null_;
infile bcp recfm=f lrecl=100 obs=5;
input;
list;
run;
