PROC FCMP creates custom functions. When the PROC FCMP code includes certain functions such as TRIM, STRIP, and LENGTH, PROC DS2 can produce memory-related errors that are similar to the following after it calls the custom function:

Operating System and Release Information

/* Create a valid path to a directory on your system */ 
libname sas_ds2 "C:\mydir";

libname base '.';

/* Create the function with_trim that contains the TRIM function */

proc fcmp outlib=base.fcmpsubs.sql_tools ;
   function with_trim($ myVal) $ 100;
     length outvar $ 100;
     outvar =trim(myVal);
     return(outvar);
   endsub;
run;

/* Create the package myfunc using the DS2-supplied FCMP package */
proc ds2;
    package myfunc / overwrite=yes language='fcmp' table='base.fcmpsubs';
run;

/* Call the st.with_trim custom function created with PROC FCMP */
package sas_ds2.dataset_info/overwrite=yes;
  dcl package myfunc st();
   method getTrimmed() returns char(100);
     declare char(100) tempStr;
     tempStr = st.with_trim('String to Trim  ');
     return tempStr;
   end;
endpackage;

/* Call the f.getTrimmed method from the previous step */
data _null_ ;
  declare package sas_ds2.dataset_info f();
  declare char(100) varlistOut;
  method init();
    f = _new_ sas_ds2.dataset_info();
    varlistOut = f.getTrimmed();
  end;
enddata;
run;
quit;
