Hi Chris,
Thank you for your message. Is there any way that I could merge all the 5000 output tables in one along each ods output step, e.g merge table 1 and 2, then merge with table 3, etc. Even each of my single table is very small (3 rows and 6 columns), merging 5000 tables at once seems to be inefficient.
Thanks, Mai
Hi Christ,
As most of my temp- datasets are in work folders, could you please show me the code that points to the Work folder instead of Arima folder as shown in your step 4:
libname arima "c:\projects\arimaout";
Thanks, Mai
Yes, here is a more complete example. This works well if your output tables can all be named with a similar prefix -- for example, "AR". This is a complete example that you should be able to run as-is to see how it works.
/* create a temp subfolder in WORK and assign a library to it */
options dlcreatedir;
%let outdir=%sysfunc(getoption(work));
/* temp library is ARIMA */
libname arima "&outdir./arima";

Wonderful! You really save me. Thank you so much Chris.
