Subject:      commas in a macro variable
Content-Type: Text/Plain; charset=US-ASCII

Hi,
I am building a SAS macro that will call
PROC CALIS.  However, some of the PROC
CALIS statements require the use of commas,
as a delimiter.  An example STD statement
from PROC CALIS:
 
STD
 e1 = u1,
 e2 = u2,
 e3 = u3,
 f1 = phi11;
 
What I would like to do is place the
PROC CALIS STD statement in a macro
variable that is initialized in a
%macro statement.  However, the %macro
statement also uses commas as a delimiter,
but in this case commas separate macro
variables.  Obviously the following code
will not yeild a macro variable called
STD with the desired syntax (as above).
 
%macro test
 (data = _last_,
  std  =
  STD
    e1 = u1,
    e2 = u2,
    e3 = u3,
    f1 = phi11);
 
Here the commas in the STD statement
are interpreted by the %macro statement
as delimiters between successively
declared macro variables.  Does anyone
have any thoughts about an elegant solution?
 
TIA
