Hi, i have a problem with the dimension definiton of an array. My code works good in SAS Guide, but in the bash does't works.  The macro variables nvars and obs are definited as:   data _null_; set sashelp.vtable (where= (memname='ABT_DUMMY'));  call symput('nvars', nvar-1);  call symput('obs', nobs);  run;   I wish to put the macros in array dimension:   data bt_lambda (keep= var dot);         array xx[&nvars.] x_1-x_&nvars.;         array xd[&obs., &nvars.] _temporary_; run; But return the errors:     The code works if i defined the macros as: %let nvars=23; %let obs=84000; But i need the dynamical dimension. Someone can tell me a solution?   ... View more
