Pro C - Select abc into :cds returns value but strcpy(cds, 'test' did not

Question

Dear All
I have a test.pc program at Unix as follow:
varchar cds [11];
varchar xyz [30];
varchar fxo [11]
main(argc, argv)
int argc;
char **argv;
find_sp_inv ();
ins_inv();
find_sp_inv()
EXEC SQL SELECT inv_no into :cds
FROM sup_inv
WHERE REF_NO = 12 ;
cds.arr[cds.len] = '\0';
EXEC SQL DECLARE cinvno CURSOR for select inv_type from inv_types
where ref_no = 12;
EXEC SQL OPEN cinvno;
for (i=0;i<3;i++) /* max three inv_type needed only against one reference */
/* invoice types may be one, two or three against one ref_no so need loop */
EXEC SQL WHENEVER NOT FOUND GOTO notfoundd;
EXEC SQL FETCH cinvno into :fxo;
fxo.arr[fxo.len] = '\0';
strcat((char*)xyz.arr,(char*)fxo.arr);
notfoundd:
printf("%-30sn\", xyz.arr) /* prints the value .. printing fine */
return;
ins_inv()
EXEC SQL
INSERT INTO inv_reference (ref_NO, ref_types)
SELECT :cds, :xyz from dual;
return;
} /* end my program */
**So it only picks Value of :cds an did not :xyz value? why please explain me ( i mean help me out).**
**Kind regards.**
