If this is what you typed then it won't have worked and you will have
seen error messages like this....

. set memory = 700Mb
'=' found where integer expected

...and the amount of memory allocated to Stata will remain at 10Mb
(according to the error message you have posted).

See -man memory- for the correct syntax which when executed will show
you how much memory you have allocated...

. set memory 700M

Current memory allocation

                    current                                 memory usage
    settable          value     description                 (1M = 1024k)
    set maxvar         5000     max. variables allowed           1.909M
    set memory          700M    max. data space                700.000M
    set matsize         400     max. RHS vars in models          1.254M

It might be worth taking a moment to read -man syntax- so that you
understand the syntax structure of Stata commands, otherwise you'll
likely find you get quite frustrated over simple things like this.
