Adding trailing blanks to alphanumeric characters SAS code

[RW9]

Hi,

data want;

  length b $200;

  a="ABCD1234";

  b=repeat("0",20-length(strip(a)))||strip(a);

run;

For trailing, just move the strip(a) before the repeat.

data want;

  length b $20;

  a="ABCD1234";

  b=a;

run;

Oh, trailing blanks, I should read the question more thoroughly.

hi ,

i want to export to Csv file after coding

sso we use something like dat_null_

AAnd put function now length is $12.

and it shd be A25

If you are using DATA _NULL_ and a PUT statement to write out the data, it is easy to write out trailing blanks.  Add a format specification to the PUT statement, for example:

put varname $25. ','  ... more variables ...;

This will write a total of 25 characters for VARNAME, including trailing blanks as needed to reach that length of 25.

Good luck.

Why?  You mention writing a CSV, but by definition a CSV file would normally NOT have trailing blanks.
