One possibility would be to convert your variable into a string
variable (if it isnt' one already), then create an indicator for
appearances of sevens:

*--------------------------------------
input nnaadd
1234
3456
6543
7777
777
77
1267
end

tostring nnaadd, g(strnnaadd)

gen seven=strmatch(strnnaadd, "*7*")
tab seven
*--------------------------------------
