Hi,

 

I have a very basic question about macros. I am trying to write a simple macro to merge two datasets. My code looks like this

 

%macro form_merge (form);

proc sql;

create table _%form as

select a.%form,a.var1

from work.data1 as A left join work.data2 as B

run;

%mend form_merge;

 

%form_merge (X);

 

However, it is not working. For the 'create table' line, I get the warning "Apparent invocation of macro FORM not resolved", and the error "22-322: Syntax error, expecting one of the following (, '-'..."

 

When I run this as just regular code (i.e., substituting X for %form), it works fine. Can someone please tell me what I'm doing wrong?

should be create table _&form 

 

and not create table _%form 

 

And the same in

select a.&form.,a.var1

 

and not select a.%form,a.var1

Oh dear, that's embarrassing. Thanks! (this is the first macro I've ever written)

@Mogreenly I wrote this last week and would appreciate any feedback if you have some time. 

It's a short tutorial on making a macro, based on the concept of working code though.

If it doesn't make sense at all that's worth knowing as well!
