Pok, It is my opinion that SAS is not very good for working with financial data.
On the other hand, I do not understand your program.  I have never seen the
INPUT function used without an explicit format.  The manual also specifically
cautions against calling INPUT with numeric arguments.  There is a slight
difficulty (probably a typo) when you read in AMT1-AMT, rather than AMT1-AMT3.
I suspect that if you change your program to create an output dataset and run
PROC CONTENTS on it, you will find that both T and TEST are character variables,
but I do not see how that will produce the results you report.

 Sas-Lers:
 
I have a very simple program but the output is a little bit confuse to me.
 
Here is the program and result:
 
data _null_;
input pay1-pay3 amt1-amt p a;
 
pay=pay1+pay2+pay3;
amt=amt1+amt2+amt3;
 
test=input((100*pay)/amt);
t=input((100*p)/a);
 
put pay= amt= test= p= a= t=;
cards;
604.64  4733.77  586.59  15  95  15  5925  125
;
 
Results:
 
...
 
pay=5925 amt=125 test=4739 p=5925 a=125 t=4740
 
...
I run this program on both mainframe machine and Unix machine.
Why value for test is deferent for t on mainframe machine?
why same value for test and t if I run this program on Unix?
 
Thanks for you help.
