HOST INTERFACE

	datatypes.library provides an ARexx function host interface that
enables ARexx programs to take advantage of the features of data
types. The functions provided by the interface are directly
related to the functions described herein, with the differences
mostly being in the way they are called.
The function host library vector is located at offset -30 from
the library. This is the value you provide to ARexx in the
AddLib() function call.

FUNCTIONS

	ExamineDT(FILENAME/A,VARIABLENAME,STEM/S,VAR/S)

	/* datatypes.rexx */
