Case change in SAS

[librasonali]

hi , 

i have one final dataset "member" which is creating a flatfile xyz.csv 
now i have few of the fields in xyz.csv  of different case i want them to be all in same case as my previous flat file. 

expected	current
Partner_ID	Partner_ID
CUST_SEG	cust_seg
SBSCR_SSN	sbscr_ssn
depn_nbr	DEPN_NBR
first_name	FIRST_NAME
last_name	LAST_NAME
pat_dob	pat_dob

In which step do you define the names in your SAS dataset?

And how do you create the flat file?

Please supply the respective codes, especially the one for the export.

i solved the issue. i was thinking some effective way but i just used as simply.

These look like variable names.  I want to point out that SAS is case-insensitive to names, so that 

first_name, FIRST_NAME, First_Name, and FiRsT_NaMe all represent the same variable.

I don't know why you want to change the case of the names, but perhaps it is so that printed output looks nicer. In that case, consider using the LABEL statement to add labels for the variables. For example,

data have;
label first = "First Name"
      last = "Last Name";
first = 1;
last = 10;
run;

proc print data=Have label;
run;
