Problem Note 64671: The FCMP procedure in a DBCS-encoded session for SAS® 9.4M6 (TS1M6) truncates the return length value to 8 bytes
 |  |  |  |  |
Running PROC FCMP in a double-byte character set (DBCS) encoded session in SAS 9.4M6 truncates the length of any return value to 8 bytes.
The following code example demonstrates this problem:
options cmplib=(work.funcs);
proc fcmp outlib=work.funcs.test trace;
function test_func();
array inputargs[1] $32;
array outputargs[1] $32;
_ret = .;
function test_func();
array inputargs[1] $32;
array outputargs[1] $32;
_ret = .;
call test_sub(inputargs, outputargs);
put "--outputargs after subroutine call";
put outputargs[1]=;
return(_ret);
endsub;
put outputargs[1]=;
return(_ret);
endsub;
subroutine test_sub(inargs_list[1] $, outargs_list[1] $);
outargs outargs_list;
/* length outargs_list $ 32; */ /* Uncomment this line for a workaround */
outargs_list[1] = "I_am_an_output_value";
endsub;
quit;
outargs outargs_list;
/* length outargs_list $ 32; */ /* Uncomment this line for a workaround */
outargs_list[1] = "I_am_an_output_value";
endsub;
quit;
data temp;
a=test_func();
run;
a=test_func();
run;
The code returns the truncated value as shown here:
--outputargs after subroutine call
outputargs[1]=I_am_an_
outputargs[1]=I_am_an_
The following is the expected, correct output:
--outputargs after subroutine call
outputargs[1]=I_am_an_output_value
outputargs[1]=I_am_an_output_value
A workaround is to explicitly set the length of any OUTARGS statements. In the above code example, when the highlighted LENGTH statement is uncommented, the values are not truncated.
This issue does not affect single-byte encoded SAS sessions.
