Oracle Message PCC-00028 - Option string not legal as EXEC ORACLE OPTION

ERROROption string not legal as EXEC ORACLE OPTION
CAUSEA precompiler option was specified inline in an EXEC ORACLE statement. Some options can be specified only on the command line. For example, INAME cannot be specified inline.
ACTIONRespecify the precompiler option on the command line, instead of in an EXEC ORACLE statement. To see an online display of the precompiler options, enter the precompiler command (with no options) at the operating-system prompt.
