Address-Conversion Routines
Address-Conversion Routines
An address-conversion routine converts one address type to another address type.
The pTAL privileged routine $AXADR on page 15-26, supported only by the pTAL
compiler, is also an address-conversion routine.
Character-Test Routines
A character-test routine tests the right byte of an INT value for an alphabetic, numeric,
or special character, returning a true value if the character is there and a false value
otherwise.
