PROC FCMP requires a three-level argument when specifying the output dataset in which the compiled function/subroutine should be stored.
But when using those compiled functions SAS requires a two-level argument for the global option CMPLIB.

The documentation says:

Note: Subroutine and function names must be unique within a package. However,
different packages can have subroutines and functions with the same names. To select
a specific subroutine when there is ambiguity, prefix the subroutine name with the
package name and a period (.) For example, to get the MthFncs version of inverse,
use MthFncs.inverse

But I haven’t been able to reproduce that behaviour. When doing:

proc fcmp outlib=work.functions.pkg1;
  function test(var1, var2); 
    return (var1+var2);
  endsub;
run;
proc fcmp outlib=work.functions.pkg2;
  function test(var1, var2);
    return (var1*var2);
  endsub;
run;
option cmplib=work.functions;
data _null_;
  a=test(3,3);
  b=pkg1.test(3,3);
  c=pkg2.test(3,3);
  put a= b= c=;
run;

The program crashes and says:

ERROR: DATA STEP Component Object failure. Aborted during the COMPILATION phase.
31    b=pkg1.test(3,3);
        _________
        557
ERROR 557-185: Variable pkg1 is not an object.

Isn’t this the way packages are meant to be used? Am I doing something wrong? Looks like yes 🙂 but I can’t see what.
Thanks!

    The following whitepaper says that there is no way to get a datastep to use same-named functions from multiple packages within a single datastep (page 15 under the heading “STORING AND SHARING FUNCTIONS”):

    http://support.sas.com/resources/papers/proceedings09/147-2009.pdf

    It does however provide some alternate suggestions.
