SQL identifier

Hi,

I have a proc-code(oracle 8i) ,
while compliling i am getting following error:

Warning at line 2540, column 23, file dil_gen_en_02.pc:
EXEC SQL DECLARE en_find_cursor CURSOR FOR S1;
......................1
PCC-W-02332, attempted to redefine SQL identifier


I want to know what is the significance of SQL identifier so that i can track the cause of this error?

Thanks in advance.
