We present here the final results of experiments searching for neutrino oscillations, carried out by the CHARM Collaboration. The data — taking took place in 1983. The first experiment was performed by exposing two detectors simultaneously to the CERN PS low energy
v
µ beam. In the second experiment the full CHARM detector was exposed to the wide-band horn-focused
v
µ beam of the CERN SPS. Complete details of the experiments and data reduction are presented. No statistically significant signals for neutrino oscillations were observed. Our 90% CL limits in the appearance experiment (
v
µ
v
e
) exclude
m
2
0.19 eV
2 for complete mixing (sin
22
=1), and sin
22
0.008 for the region
m
230 eV
2. These results, and the limits observed for (
v
µv
x
) (disappearance of (
v
µ), are in agreement with those of most other experiments but exclude part of the region previously reported as a possible indication of
v
µv
e
oscillations.
