I went thru a white paper (not sure), Paper 195-25
Multiple Users to Update the Same Data Set in the Windows Environment.
But,I am not very sure on how to use SAS/SAHRE libname assignment. So, I
am trying to implement example 3 (macro code without using SAS/SHARE)
given in this paper. But, I like to add another check to see if the
dataset is avilable for writing. Is there a way to check this?
Also, I looked into CNTLLEV= option (dataset option). SAS Documentation is
By default, SAS procedures permit the greatest degree of concurrent access
possible while they guarantee the integrity of the data and the data
analysis. Therefore, you do not normally use the CNTLLEV= data set
Please suggest me...
