Proc Export: Removing spaces in generated file

[sg16773]

Hi,

I have multiple sas datsets(~30) present in a directory and need to convert all these into text files.  I am using the code below for same:

=====================================================

LIBNAME Test "D:\";

%MACRO Convert2CSV(Libname);

DATA MEMBERS;
SET SASHELP.VMEMBER(WHERE=(LIBNAME = "&Libname"));

RETAIN OBS 0;
OBS = OBS+1;

KEEP MEMNAME OBS;

RUN;

PROC SQL;
SELECT MIN(OBS) INTO :MIN
FROM MEMBERS;
QUIT;

PROC SQL;
SELECT MAX(OBS) INTO :MAX
FROM MEMBERS;
QUIT;

%Local D;

%DO D = &MIN %TO &MAX;

PROC SQL;

SELECT COMPRESS(MEMNAME) INTO: Table
FROM MEMBERS
WHERE OBS=&D;

QUIT;

PROC EXPORT DATA=&Libname..&Table DBMS=dlm replace
OUTFILE="D:\_today\&Table..txt";
delimiter="|";
RUN;

%END;

%MEND;

%Convert2CSV(TEST);

==================================================================

Note: I have leveraged this code from (https://communities.sas.com/t5/SAS-Programming/Export-multiple-tables-from-SAS-to-csv/td-p/27090)

Issue: The generated text files have spaces in the name. For eg: 'myfile.sas7bat' gets converted to 'myfile    .txt'

Just a hunch but I think the generated filenames are of fixed length. Therefore to meet the length, SAS is introducing spaces. How do avoid this?

Ask: I need help in removing the spaces from the generated file name. I have tried using the Trim function but it doesn't seems to be working.

Thanks,

Why don't you just do it in one data step that creates the exports with call execute?

data _null_;
set sashelp.vmember (where=(libname = "TEST"));
call execute('
  proc export
    data=' || strip(memname) || '
    dbms=dlm
    replace
    outfile="D:\_today\' || strip(lowcase(memname)) || '.txt"
  ;
  delimiter="|";
  run;
';
run;

Hi KurtBremser,

Thanks for your response. I tried the code you suggested but I am getting the following error(screenshot below). May be the code is not able to search the dataset in the defined library("TEST").  

Apologies for the silly questions but I am very new to SAS and trying to learn the language.

I forgot to add the libname in my call execute. Expand the call execute like this.

call execute("
  proc export
    data=test." || strip(memname) || "
    dbms=dlm
    replace
    outfile='D:\_today\" || strip(lowcase(memname)) || ".txt'
  ;
  delimiter='|';
  run;
";

Note that I also changed the usage of single and double quotes, to facilitate the use of a macro variable/parameter if you later want to wrap the whole data step into a macro definition for easier reuse.

Thanks KurtBremser!

This did the trick 🙂
