INTEGER

[IntType] [UNSIGNED] INTEGER[n]

[IntType] UNSIGNEDn

An n-byte integer value. Valid values for n are: 1, 2, 3, 4, 5, 6, 7,or 8. If n is not specified for the INTEGER, the default is 8-bytes.

The optional IntType may specify either the BIG_ENDIAN (Sun/UNIX-type, valid only inside a RECORD structure) or LITTLE_ENDIAN (Intel-type) style of integers. These two IntTypes have opposite internal byte orders. If the IntType is missing, the integer is LITTLE_ENDIAN.

If the optional UNSIGNED keyword is missing, the integer is signed. Unsigned integer declarations may be contracted to UNSIGNEDn instead of UNSIGNED INTEGERn.

Example:

INTEGER1 MyValue := MAP(MyString = '1' => MyString, '0');
       //MyValue is 1 or 0, changing type from string to integer
UNSIGNED INTEGER1 MyValue := 255; //max value possible in 1 byte
UNSIGNED1 MyValue := 255;
       //MyValue contains the max value possible in a single byte
MyRec := RECORD
  LITTLE_ENDIAN INTEGER2 MyLittleEndianValue := 1;
  BIG_ENDIAN INTEGER2 MyBigEndianValue := 1;
       //the physical byte-order is opposite in these two
