Formal parameter &V1& is not of the same data type as the argument &V2&
entered with it.

System Response

The cursor marks the entry for a table/function that is incorrect.

How to fix this error?

A table is referred to by the keyword TABLE, the language-independent
table name, and a list of arguments, each consisting of <Formal
parameter = Arg>, for example:
TABLE TEST_TAB(COLOR='red', PRICE=PRICE_1)
COLOR and PRICE are formal parameters of the table, 'red' is a constant
and PRICE_1 is a characteristic-specific variable.
A function is identified by the keyword FUNCTION. The other entries are
the same as for a table, for example:
FUNCTION TEST_FUN(COLOR='red', PRICE=PRICE_1)
The data type of each argument must be the same as that of the formal
parameter. If COLOR is an alphanumeric characteristic (CHAR) in table
TEST_TAB, for example, you cannot enter a figure as an argument. Check
argument &V2& for formal parameter &V1& and correct the error.
