If you don't care about preserving the distinction between "missing" and "not available", then

    destring variable1-variable200, ignore("missingnotavailable") replace

is quickest.  Alternatively, if you want to preserve the distinction, try:

    ds variable1-variable200, has(type string)
    foreach var of varlist `r(varlist)' {
        replace `var' = ".a" if strpos(`var',"missing")
        replace `var' = ".b" if strpos(`var',"not available")
        destring `var', replace
    }
