{ DASTRSHORT
This takes an integer date value and returns a string with
month and day of week abbreviated.
If WITHDAY is passed as true then the returned string will
include the day of the week, otherwise only month, day and
year will be returned.
The following global types must be declared:
TYPE string255 = string 255;
byte = 0..255;
The following additional procedures must be declared:
PROCEDURE breakdate;
PROCEDURE setlength; external;
}
