How many dataset we can use in one to one merge in sas data step .

[Loko]

Hello,

as per the documentation of SAS (http://support.sas.com/documentation/cdl/en/basess/58133/HTML/default/viewer.htm#a001304305.htm),

under Understanding the MERGE Statement it is stated:

"SAS-data-set-list is the names of two or more SAS data sets to merge. The list may contain any number of data sets"

[Kurt_Bremser]

According to Step-by-Step Programming with Base SAS(R) Software, there seems to be no fixed limit:

The list may contain any number of data sets.

But you may run out of resources with very large numbers of datasets; you can only confirm this by testing.
