Chapter 2  Mathematical Functions and Procedures 

This chapter describes the mathematical functions and procedures in
alphabetical order.


NOTE  The function names ending with a prime (EXTIN', for example) can be
      called by HP Pascal programs using the ALIAS command with the
      EXTERNAL or INTRINSIC statements.  For example, here is a
      declaration that uses ALIAS with EXTERNAL:

             PROCEDURE EXTIN $ALIAS 'EXTIN"' $(
                     ANYVAR charstring : bytearray;
                        VAR stringlen  : SHORTINT;
                            decplaces  : SHORTINT;
                            datatype   : SHORTINT;
                            scale      : SHORTINT;
                            delimiters : SHORTINT;
                     ANYVAR result     : INTEGER;
                        VAR error      : SHORTINT
                          )
           EXTERNAL;

      The next example illustrates the preferred approach of using ALIAS
      with INTRINSIC:

           PROCEDURE EXTIN $ALIAS 'EXTIN"'; INTRINSIC;

      In HP FORTRAN 77/XL, you must declare routine names with a prime,
      as follows:

           $ALIAS EXTIN = 'EXTIN"'(%REF, %REF, %VAL, %VAL, %VAL,
           %VAL, %REF, %REF)"
