how to reduce repetion of proc

[kashili]

I need to call a proc with different argument. In my code below, I have to change

1)value of p in each model statement

2)numeric value in the title.

It seems I cant do it in do loop. Should I use macro or is there a better way of reducing this repetitive code.

thank you

title "arch=1";

proc autoreg data=Ethylene maxit=2000;

model ret = /  nlags=2  noint garch=(p=1);

run;

title "arch=2";

proc autoreg data=Ethylene maxit=2000;

model ret = /  nlags=2    noint garch=(p=2);

run;

title "arch=3";

proc autoreg data=Ethylene maxit=2000;

model ret = /  nlags=2    noint garch=(p=3);

run;

title "arch=4";

proc autoreg data=Ethylene maxit=2000;

model ret = /  nlags=2    noint garch=(p=4);

run;

title "arch=5";

proc autoreg data=Ethylene maxit=2000;

model ret = /  nlags=2    noint garch=(p=5);

run;

title "arch=6";

proc autoreg data=Ethylene maxit=2000;

model ret = /  nlags=2    noint garch=(p=6);

run;

Hi,

Below macro will avoid reptitive use of proc but i don't know whether this the better way of reducing.

%macro proc_rep(p=);

%do i=1 %to &p;

title "arch=&i";

proc autoreg data=Ethylene maxit=2000;

model ret = /  nlags=2  noint garch=(p=&i);

run;

%end;

%mend;

%proc_rep(p=6);

The AUTOREG procedure supports multiple MODEL statements.  Each can have its own label.  This allows a single read of the data.
