using SUM FIELDS option in SORT

[deleted_user]

Hi,
We use SAS under Z/OS environment. I have a requirement to summarize (calculate counts on one or more fields) input file. For example the input file,

ID MNAME CITY

001 SANTA DENVER
002 DERMETT LAKE CITY
001 SANTA DENVER
002 DERMETT LAKE CITY


The summarized output will be:


ID count
----------------
001 02
002 02

ID MNAME COUNT
------------------------------------
001 SANTA 002
002 DERMETT 002

The output shown above is sample only.. need to get unique counts on combination of one or more fields.

I thought of doing it in SYNCOSORT SUM FIELDS option but need to execute multiple steps.

Could you help me how can I achieve this result in SAS?

Can we use SYNCSORT control statements in SAS?

Thanks in advance

Hi:
You may not even need SYNCSORT. PROC FREQ with the NLEVELS option will give you this information. See this previous forum posting. The example output appears before the code that generated the output:
