Select Data between two values

[MirLuie]

Hey Guys!

sorry for my english.. i try my best 🙂

Does someone know, how to select all data from my table:

between (AE = "A" AND AE = "E")  OR between (AE = "A" AND AE = "B")   OR  between (AE = "B" AND AE = "E") OR  between (AE = "B" AND AE = "B")

There are As for Start, Es for End or Bs for either Start or End in the data set.

I just like to select the rows between an A and an E (or A and B or B and E or even B and B) and put them in a new table.

so like: when AE is A: take all lines after (in time) until AE is E and put them in a new table

Table is sorted by IPID and than by measurement_time.

please look at the pic attached.

thank you very much!

Untested; when you post a question like this, you should provide your test data in the form of a data step, so I can recreate it to try the program;

Tom

data SetSwitch;
	retain KeepSwitch 0;
	set Have;

	if AE = "A" then KeepSwitch = 1;
	else if AE = "E" then KeepSwitch = 0;
	else if AE = "B" & KeepSwitch = 1 then KeepSwitch = 0;
	else if AE = "B" & KeepSwitch = 0 then KeepSwitch = 1;
run;

data SetVar;
	set SetSwitch;

	if KeepSwitch = 1 then if AE = " " then AE = lag(AE);
run;

data Want;
	set SetVar;

	if AE ^= " " then output;
run;
