^DATATYPE(position)
Arguments
position
The ordinal position of the argument whose data type will be returned. (n)
Discussion
^DATATYPE returns the data type of an argument as one of the following values, which are defined by the compiler:
D_TYPE_A = 1 Alpha
D_TYPE_D = 2 Decimal
D_TYPE_ID = 4 Implied-decimal
D_TYPE_I = 8 Integer
D_TYPE_P = 32 Packed
D_TYPE_IP = 36 Implied-packed
D_TYPE_OBJ = 24 Object handle
Use the .IS. operator to determine a specific type of class. (See Object operators for more information about .IS..)
|
In Synergy .NET, ^DATATYPE is not allowed on MISMATCH a arguments; it should only be used on MISMATCH n arguments. (See the ”Parameter definitions” Discussion for more information about using ^DATATYPE with MISMATCH.) |
Examples
subroutine stringval
a_results ,a
;Implied second parameter
proc
if (^passed(^arg(2))) then
begin
using (^datatype(2)) select
(D_TYPE_A),
a_result = "String is " + ^arg(2)
(D_TYPE_D, D_TYPE_I),
a_result = "Value is " + %string(^argn(2))
(),
a_result = "Value is invalid"
endusing
end
else
a_result = "String or value not passed”
xreturn
endsubroutine
