Hi Maurice,
If the AUTORECODE ../GROUP is not what you wish (ie your numeric codes have some specific meaning).
SORT your external system file by the string variable and save it.
Transform your master file from wide to long using VARSTOCASES retaining caseidentifier and string and index.
SORT by string.
MATCH FILES using the external file as a table with the string as a key.
transform the file from long to wide.
Done.
HTH, David

dear fellow list visitors,

please help me with this problem.
I have the following syntax which works perfectly.

It 'replaces' strings in old variables (name1 to name14) into
numerical ones in a new variable (newname1 to newname14).

example:
vector name=name1 to name14.
vector newname(14).
loop i=1 to 14.
do repeat a="alpha" "beta" "gamma" / b=1 2 3.
- if name(i) = a newname(i)=b.
end repeat print.
end loop.


However, instead of three values (alpha beta and gamma) I have
thousands of unique string values stored in a separate system file,
each identified with a unique numerical code.
How can I insert these values in the do repeat function (after 'a='
and after 'b=')?

The reason why I want to change these from string to numeric ones is
that I know the system file will be smaller and hopefully also faster
to read.

You help is much appreciated.

sincerely
Maurice
