Re: how to sort variable by character variable first then numeric #3
Karen, Assuming that Mark is correct and you want to change the order of your variables, rather than sort the data, then you could also accomplish it with a retain statement before your set statement. E.g., data sample; StudentID='A1'; Score=78; Gender='M'; Address='123 Cherry Tree Lane'; output; StudentID='B2'; Score=79; Gender='F'; Address='456 Cherry Tree Lane'; output; run; data want; retain StudentID Gender Address Score; set sample; run; Art ------- On Sat, 26 Apr 2008 09:00:23 -0700, Karen <irain168@GMAIL.COM> wrote: >Hi, > >who knows if we can use SAS to sort the variables by character >variable first and then numeric variable. > >Such as: >The original order is: >StudentID Score Gender Address > >I want to sort it as > >StudentID Gender Address Score > >Any hint? > >Thanks very much! ...

Re: how to sort variable by character variable first then numeric #2
Hi Karen, There are many variations but here are a couple. data sample; StudentID='A1'; Score=78; Gender='M'; Address='123 Cherry Tree Lane'; output; StudentID='B2'; Score=79; Gender='F'; Address='456 Cherry Tree Lane'; output; run; We can order the columns specifically, AND we can order the columns by CHARACTER then NUMERIC. Below are examples of both. There are several ways to order the column in specific order: * SQL order as you list them ; proc sql; create table result1 as select StudentID, Gender, Address, Score from sample ; quit; * datastep compiler order them in ; * the order they are incurred. ; * i.e. LENGTH found before SET. ; data result2; length StudentID $2 Gender $1 Address $20 Score 8 ; set sample; run; Here is one way to order by CHAR then NUM. * ordering by character then numeric ; data result3; set sample(keep=_character_); set sample(keep=_numeric_); run; Hope this is helpful.

Variable in variable?
Hello, I think that what I'm trying to do is impossible, but before I give up I thought I'd try and pick a few more knowledgeable brains than my own. I have any array of user defined type variables. I need to loop through the array (doing certain calculations) on a particular member variable. I then want to loop through the array again on a different member variable doing very similar calculations. I only need to change a couple things in the loop, otherwise the loop is identical from one member to the other. In a nutshell, what I'm trying to do is use a variable, that will change its contents accordingly, that I will use to rename the member within the array. This seems harder to explain than perhaps showing an example: ArryName(index).MemberName '----standard syntax for refering to a varibale within an array of user defined type. 'I declare another variable to hold the changing member name that will be used on repeating iterations through the same loop (using nested loops) Dim ChangingMemberName as String ChangingMemberName = ".MemberName1" '1st iteration ArryName(index).ChangingMemberName '2nd iteration ChangingMemberName = ".MemberName2" ArryName(index).ChangingMemberName This code does not work and only generates errors. It would appear that trying to rename a member within an array with another variable is not possible but the efficiencies to be gained are ...

Variable variables?
I have a situation which I 'think' I need to use variable variables and not sure how to go about it. I have several <select multiple> elements on a search form with their names created dynamically and the options created dynamically. $parent holds the name such as "Women", "Mens" etc.. $c_id holds category_id and is sent off as the 'value' of the option. This form is self calling and an array is created for the multiple option selected. Women => array([0]=>20,[1]=>21,...) Mens => array([0]=>32,[1]=>35,...) I am using in_array() to check returned posted values against an id. How do I reference that array by using the value of $parent. if $parent is 'Women' I need to reference the array 'Women' Here is a nutshell of the algorithm. foreach($parent_ary as $parent) { echo "<select {$parent}[] multiple>"; foreach($category_ary as $c_id=>$category) { if(in_array($c_id, array of posted value)) { // Create select option } else { // Create regular option } } echo "</select>"; } I hope this makes sense and yes I did RTM but could not transpose what they where explaining to what I need to do.

VARIABLE (was is VARIABLE does ? )
Charles Melice raises an interesting question when he asks why VARIABLE is in the CORE wordset. Andrew Haley responded that CORE is not intended to be a minimalist wordset. We have in the past had some discussion re: proper selection of a minimal set of words. Does anyone think there is merit to the suggestion of adding a minimal-CORE wordset to the revised Standard (whenever that happens)? The virtue of a Standard minimal word set would be the virtue we have (albeit with some exceptions) found in having a Standard Forth, namely virtually painless portability and inter-operability. I, for o...

Re: how to change the character variable to numerical variable?
You just need a data step and fill in using variable names that apply to your data. data test; a = '123.4'; b = input(a,8.); run; proc contents; run; Keep in mind that you have to create a "new" numeric variable. That is you cannot "convert" A in the example above to numeric.

Re: How to transfer character variables into numeric variables by
Chiu-Chen, There is no way easy way to get SAS to do what you want. The problem will coms in since you have some vars that are true character variables, some that are true numerics held as characters, and here is the problem some that are a mixture of character and numeric and right fully held as character. If I understand you correctly you have all vars as character. Thus any mass indescriminant conversion will give you errors in your log and not a good error at that. To do what you want all you need is a few simple things, first a list of the numeric variables held as text that you want converted to numeric, second a rename statement, length statement,, a drop statement on th eoutput side of things, and lastly an assignment statement. data one ; infile cards dsd dlm = ' ' ; input x1 $ x2 $ x3 $ x4 $ ; cards ; A 1 1 1 B 2 B 2 C 3 C 3 D 4 4 4 ; run ; data two (drop = _:) ; length x2 x4 8. ; set one (rename = (x2 = _x2 x4 = _x4)) ; x2 = _x2 ; x4 = _x4 ; run ; proc contents ; run ; Now if you have a lot of vars you need converted this process can be made easier by the use of either macros and/or arays.

Hi Chen, I have a macro that does that, while "preserving" original variable names and attributes like labels. You can specify more than one variable at a time, while you may also specify no-numeric values and their corresponding new numeric values to be replaced by.
