Appending csv files in SAS -

-

i have bunch of csv files. each has data different period:

filename file1 'jan2011_price.csv'; filename file2 'feb2011_price.csv'; ...

do need manually create intermediate datasets , append them together? there better way of doing this?

solution

from documentation preferable use:

data allcsv;        length fileloc myinfile $ 300;        input fileloc $ ; /* read instream data       */        /* infile statement closes current file           , opens new 1 if fileloc changes value           when infile executes                        */        infile filevar=fileloc                filename=myinfile end=done dlm=',';         /* done set 1 when last input record read  */        while(not done);       /* read input records  */       /* opened input file                          */          input col1 col2 col3 ...;          output;        end;        put 'finished reading ' myinfile=;  datalines; path-to-file1 path-to-file2 ... run;

to read bunch of csv files single sas dataset, can use single data step described in sas documentation here. want second example in section uses filevar= infile option.

there should no reason create intermediate datasets.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
