 tw_ASay( wT, wL, aray, attr1, attr2 )
 ----------------------------------------------------------------------------
     Display an array of strings at a given screen location with
     optional embedded colours. The strings are displayed on successive
     screen lines. The programmer MUST ensure output remains in bounds.
     This function uses direct screen writes and therefore will not obey
     Clipper's DISPBEGIN(), DISPEND() sequence.

       Arguments:

     wT,wL - 'N' Screen coordinates at which to begin the display. The
                 first array element is displayed at ( wT, wL ), the
                 next at ( wT + 1, wL ) etc.

     aray  - 'A' Array of strings to display. The strings may include
                 the '..' delimiters which signal display in the
                 secondary attribute, attr2.

     attr1 - 'N' Primary display colour attribute. Correct numbers may
                 be found with a return from twVAttr( cColour ).

     attr2 - 'N' Secondary display colour attribute. Correct numbers
                 may be found with a return from twVAttr( cColour ).
                 This parameter MUST be given with tw_ASay(), even if
                 it is the same as attr1.

       Return:

     None.

       Example:

     tw_ASay( 3, 4, {"now .is the. time",;
                     "for all .good. men",;
                     "to switch to .Clipper.." },;
                     twVAttr( "w+/b" ), twVAttr( "gr+/r" ))
