AmigaE/OBJECT

 the compound type (OBJECT)
----------------------------
OBJECTs are like a struct/class in C/C++ or a RECORD in pascal. Example:

OBJECT myobj
  a:LONG
  b:CHAR
  c:INT
ENDOBJECT

This defines a data structure consisting of three elements. Syntax:

OBJECT 
   [ :  ]           /* any number of these */
ENDOBJECT

where type is one of the following:

CHAR/INT/LONG/
PTR TO CHAR/INT/LONG/
ARRAY OF CHAR/INT/LONG/

(ARRAY is short for ARRAY OF CHAR)

like DEF declarations, omitting the type means :LONG.

Not()e that  need not be a unique identifier,
it may be in other objects too. There are lots of ways to use objects:

DEF x:myobj                      /* x is a structure */
DEF y:PTR TO myobj               /* y is just a pointer to it */
DEF z[10]:ARRAY OF myobj

y:=[-1,"a",100]:myobj            /* typed lists */

IF y.b="a" THEN /* ... */

z[4].c:=z[d+1].b++

ARRAYs in objects are always rounded to even sizes, and put on
even offsets:

OBJECT mystring
  len:CHAR, data[9]:ARRAY
ENDOBJECT

SIZEOF mystring is 12, and "data" starts at offset 2.

'PTR TO' is the only type in OBJECTs that may refer to yet undeclared
other objects.

For all other OBJECT features that are somehow OO related see OO features.
