where we give the MSGSFL in rpg400?

RPG/400 number of Records present in a physical file using file information data structure FPF001 IP E DISK F KINFDS INFDS1 IINFDS1 DS I *RECORD RECORD Is this coding correct sir,i have given I P E that is I- input,P-primary file,E-externally described. Primary to use RPG logic cycle,is this the correct method because we have to find number of records present using file information data structure in RPG/400 without doing any input/output operations on the file and also without using DSPFD,SQL. If the above coding is correct means,when i compile the program it gets compiled,but if i call the program it does not return anything,i need number of records,please complete the coding sir.
