Overview of intrinsic functions

The following table lists the available functions.

The "Arguments" column defines type and number of arguments as follows:

A	alphabetic
I	integer
Ind	index
Nat	national
Num	numeric
O	object reference
P	pointer
T	type declaration
X	alphanumeric1

¹ X in the "Arguments" column contains stongly typed group items. If the argument type deter-mines the function type, then the function is alphanumeric as soon as just one of its arguments is strongly typed. This also applies if all the function’s arguments are of the same type. Strongly typed arguments are excluded for the ADDR, MAX, MIN, ORD-MAX and ORD-MIN functions.

The "Type" column defines function type as follows:

I	integer
Ind	index
Nat	national
Num	numeric
X	alphanumeric
