Annotation of OpenXM_contrib/pari/COMPAT, Revision 1.1

1.1     ! maekawa     1: This file lists the incompatible changes between Version 1.39.15 and 2.0.x
        !             2:
        !             3: * The calculator GP:
        !             4: ====================
        !             5:  - most function names have changed (see misc/new.dic or use whatnow under GP)
        !             6:  - lowercase / uppercase letters distinguished.
        !             7:  - the syntax \var = value is not recognized anymore. Use standard
        !             8:    metacommands instead.
        !             9: (setting the compatibility level "compatible" to 3, with "default" will give
        !            10: you those three back).
        !            11:
        !            12:  - strict parenthesis matching before executing the command
        !            13: (set strictmatch to 0 to get old behaviour)
        !            14:
        !            15:  - functions label / goto have been removed (use break/next/return instead).
        !            16:  - conjugation x_ has been removed. '_' can be freely used in identifiers.
        !            17:  - \k metacommand removed
        !            18:
        !            19:  - result history is now cyclic (older results are erased when the maximal
        !            20:    size "histsize" is reached).
        !            21:  - the Set() function turns objects into strings (so that set functions are
        !            22:    able to treat arbitrary objects). Use eval to turn them back to GENs.
        !            23:  - the type() function returns a string and not a number.
        !            24:  - sum(X=a,b,...,x) yields x if b<a. Analogous statement for prod.
        !            25:
        !            26: * The library PARI:
        !            27: ===================
        !            28:  - use symbolic type names (t_INT, etc.). Don't use any explicit type number
        !            29:    in your programs since these are liable to change (they have not, but will).
        !            30:  - the codewords of GEN objects have a different internal structure. The
        !            31:    components should only be accessed through the documented macros. When
        !            32:    creating codeword x[1] for the GEN x, use the eval* macros (the set* ones
        !            33:    don't fill the codeword completely).
        !            34:  - the following constant names have changed ("pari" prepended): C1, C2, C3, K,
        !            35:    K1, K2, K4. The constant C31 has disappeared.
        !            36:  - prec and defaultpadicprecision are no longer global. The latter has
        !            37:    disapeared.
        !            38:  - char *pariversion not set anymore (use the macros PARIVERSION/PARIINFO)
        !            39:  - LONG_IS_32BIT is never defined (test whether LONG_IS_64BIT is defined
        !            40:    or not).
        !            41:  - gen2str() renamed to GENtostr().
        !            42:  - gitoascii() suppressed, use GENtostr().
        !            43:  - init() renamed to pari_init().
        !            44:  - the macro mant() has been suppressed.
        !            45:  - imprimer() suppressed. output() is now a function and can be used under
        !            46:    all debuggers.
        !            47:  - the prototypes and behaviour of gredsp() and normalize() have changed.
        !            48:    They are not documented anymore.
        !            49:  - the install() function has been modified (use codes instead of valence).
        !            50:  - gpuigs only has two arguments.
        !            51:  - integ now takes two arguments, like deriv.
        !            52:  - setrand, getrand, getstack, gettime, glength return a C long, and not a GEN.
        !            53:  - pari_randseed no longer global, use setrand/getrand
        !            54:  - gerepile(ltop,lbot,0) no longer returns ltop - lbot
        !            55:  - nf[5][7] stored in two element form (was Z-basis) for faster inversion
        !            56:  - t_POL and t_POLMOD can be freely mixed as long as main variables are the
        !            57:    same (result is the expected POLMOD)
        !            58:
