It depends on the format of the .dat file. There is no standard for this file type, so we cannot guess the details.

Guessed, tha the .dat file is a text file and you want to search fpr the occurence of a string anywhere in a line:
fid = fopen(FileName, 'r');
if fid == -1
error('Cannot open file: %s', FileName);
end
key = 'YourStr';
data = 'not found';
ready = false;
lineNo = 0; % [EDITED]
while ~eof(fid) && ~ready
S = fgetl(fid);
lineNo = lineNo + 1; % [EDITED]
if any(strfind(S, key))
data = YourReadMethod;
ready = true;
end
end
fclose(fid);
