Hello Elaine...
The proc output does make sense (It's the relative position within the SAS
Dataset which is shown). But don't bother with it. It's not really important
as long as it's output meets your requirement.
In order to have a listing of the variable in the "proper order", you should
add the following statement at the end of your proc declaration :
proc contents data=MyDataset position;
run;
the "position" statement will produce a second listing but with your
variables in the desired order. The default for SAS is to print the proc
contents with the variable in alphabetical order. Usefull for many and not
at all usefull to other. Later, you'll learn how to produce the desired
output with the ODS statement and you won't hurt the environment as much.
As for formatting, you would need to consult the sas documentation under
"Features of SAS language for Windows", "Formats". It will help you a little
bit more... The problem with SAS documentation is not about the contents.
Everything is there. It's just a matter of finding it ... :-)
Hope this helps you a little bit...
Sincerely,

Objet : Basic SAS questions
Hello, I'm an MPH grad student at a university with no SAS support.
While we did have a lab on stat analysis, none of the preliminary
dataset cleaning/formatting/merging were covered, and I am unable to
get the programs to work despite referring to books and the online
help. So I hope that someone has the time to assist me with these
novice concerns! I'm using version 8.
First question: can someone tell me why my Proc contents output makes
no sense? You can see the # column is in a certain (correct) order, but
the "Pos" column is incorrect. This is from an Excel file that I
imported as a .csv file - when I look at the .csv file, the # is
correct, but Pos is not. Here's the Proc contents output : Note how
variable 1 "ID" begins at position 80, var 5 "VC" begins at position
"0", etc.
-----Alphabetic List of Variables and

3 sexunmod Char 8 96
2 testdate Char 8 88
5 vc Num 8 0
11 wt Num 8 32
17 zipcode Char 8 152
Second question: I can't figure out how to get the date formatting to
work. Here's my programming, and it keeps giving me error messages:
(I actually have 3 date variables in this dataset, but here I only used
the formatting once - using it for all 3 just produces more error
messages)
data herman;

NOTE: 696 records were read from the infile 'C:\Documents and
Settings\user\Desktop\ExpNoLabels.csv'.
The minimum record length was 89.
The maximum record length was 102.
NOTE: The data set WORK.HERMAN has 696 observations and 23 variables.
NOTE: DATA statement used:
real time 0.53 seconds
cpu time 0.24 seconds
15 proc contents;
16 run;
When I omit the mmddyy10. after variable testdate all these error
messages disappear. So what is the correct way to format dates in the
input list type of statement? (Note that I didnt want to switch to the
Input statement where each var is listed @ column position, since my
column positions are wrong in the Proc contents output - See question
1.)
Question 3:
When I use the following import procedure (using an Excel file in which
names had already been removed and the actual data begins on the first
row), even though I said Getnames=no the variable names in the
resulting file use the first row variables values as variable names.
Any idea what to do about this?
PROC IMPORT OUT= WORK.herman
DATAFILE= "C:\Documents and Settings\user\Desktop\ExpNoLabel
s.xls"
DBMS=EXCEL2000 REPLACE;
GETNAMES=NO;
RUN;
Thanks for the help! I feel like a complete bonehead since I cant even
get to the analysis part with these problems in the way.
