Great codes! It works..although I still have problems since my data is no longer that simple. Here is the new data:

Code:
MIN 0007
TOM_HA_M, 10
JOHN_U_A_IM, 0
WHAT_A_PROBLEM_J, 400

MIN 0839
JACK_MAC_D, 0
TIM_L_POP_D, 20

MIN 0100
BAN_Q_Y_O_P, 99
NAVE_U_QPP, 82

MIN 0199
BYG_LI_SEVEN, 321
SAM_O_GT, 10937
.....
.....

I need code that will give me file100 if I select MIN 0100; and this file100 contain the information:
Code:
MIN 0100
BAN_Q_Y_O_P, 99
NAVE_U_QPP, 82
