Answer / somnath

=> Symget is used to resolve macro variables in data step
and & is used to resolve macro variable in macro processing.
For example, if you have 10 macro variables name1-name10
which contains 10 names and you want to get a particular
name in a data step then you can use symget, not &.
data rank;
i=4;
run;

data name;
set rank;
name=symget('name' || left(put(i, 8.)));
run;

=> The same concept applies for call symput.

The main idea is that the routines symget and symput are
executed at sas run-time where & and %let executes at macro
run time, much before that sas executes it.

we can use parameters in cl and rpg pgms...etc.in particular i think when we use data area or datastructure or data queue .i think this means which one====in my question...parameters cannot be passed in which one????hope understand my qstn???
