Subject:      Problem replacing Macro Variables in Simulation
Content-Type: text/plain; charset=ISO-8859-1

I am trying to create a file with syntax for running an R function.
The syntax has variable file names, and is part of a simulation, so it I
have coded it within a macro. I am having problems getting the macro
variables to resolve and writing the syntax file. Any help will be
appreciated.

The following (partial code) allows creation of the syntax file, but the
macro variables do not resolve.

data _null_ ;
 file 'C:\Program Files\R\R-2.14.0\bin\runlink.r';
 PUT ' library(plink)'                                        ;
 PUT ' setwd("g:/BILOGfiles")'                    ;
 PUT ' gr.pars <- read.bilog("&ref&r..par")'           ;
 PUT ' gf.pars <- read.bilog("&foc&r..par")'           ;
 . . . ;

If I take the lines with macro variables and replace the ‘ with a macro
variable that resolves to a ‘ (e.g.,  PUT &tic write.csv
(conname,"L&foc&r..csv") &tic    ;), I get the following errors, among
others”
22: LINE and COLUMN cannot be determined.
ERROR 22-322: Syntax error, expecting one of the following: a name,
              a quoted string, arrayname, #, (, +, /, //, ;, @, @@,

I have also tried submitting the lines as %str data:
put
 %str("library("plink") ")
 %str("setwd("g:BILOGfiles")")
 %str("gr.pars <- read.bilog("&ref&r..par")")
 %str("gf.pars <- read.bilog("&foc&r..par")")
 %str("common <- matrix (c(1:&items,1:&items), &items, 2)")
. . . :

And get these errors, whether I submit the lines as a group or with
individual PUT statements:
