data want2;
  do i = 1 to 10;
  if _N_ = 1 then do ;
declare hash H() ;
   H.defineKey ("datetime") ;
   H.defineData("datetime", "temperature","pressure","nr") ;
   H.defineDone() ;
end ;
set A;
array temperature_	temperature_1	-	temperature_10;
array pressure_	pressure_1 - pressure_10;
temperature_[i] = temperature;
pressure_[i] = pressure;
end ;
drop i temperature pressure;
run;

One thing i can't do, i want the datetime variable in the table wont always be in the first position ie if i = 1; (it's not enough to cut off 9 minutes, it's just an example)

Please check if everything is ok, maybe it can be done smarter and faster because I have ower 2GB of data.

thank you in advance for your help

The logic of your data want2 step looks incomplete and doesn't really align with the little bit you tell us.

Please describe in more detail what you have and especially what you need.

As a first impression: Not sure that using a hash table is the right thing to do here starting with: Do you have sufficient memory available in your session to load 2GB of data into a hash table?

What are you trying to achieve?

What does the expected output look like?

Re: hash table transposition with arrays

It appears that you have records in groups of 10. Each group has a constant pressure unique to that group. And each group also has a constant value for NR, although the NR can be shared with other groups.

So I presume you want to convert 10 records to 1 record, such that

The record has a single variable for pressure and nr
The record has ten datetime variables and ten temperature variables.

If the above is correct, then you have a simple data step program which reads in 10 records, placing datetime and temperature values into corresponding arrays of ten variables, followed by a single output, as in:

data A;
  informat datetime  datetime21.;
  input datetime temperature pressure Nr ; 
  format datetime  datetime21.;

data want;
  do i=1 to 10; 
    set a;
	array dt  {10} datetime1-datetime10;
	array tmp {10} temperature1-temperature10 ;
	dt{i}=datetime;

But you might not like the fact that this places all ten datetime variables in front of all ten temperature variables. You might instead prefer to have 10 PAIRS of variables (i.e. datetime1/temperature1, datetime2/temperatue2, ....). If so, then:

data want;
  do i=1 to 10; 
    set a;
	length datetime1 temperature1  datetime2 temperature2  datetime3 temperature3 
           datetime4 temperature4  datetime5 temperature5  datetime6 temperature6 
           datetime7 temperature7  datetime8 temperature8  datetime9 temperature9 
           datetime10 temperature1 8;
	array dt  {10} datetime1-datetime10;
	array tmp {10} temperature1-temperature10 ;
	dt{i}=datetime;
	tmp{i}=temperature;
  end;
  format datetime1-datetime10 datetime21. ;
  drop i datetime temperature;
run;

Oh, and thank you very much for provided the needed data in a data step form.
