Changes

Date           Version

2010-06-05   1.1.3
'call' instructions were not recognized. Now they compile either
to 'acall' or 'lcall', depending on address range.


2010-04-19   1.1.2
Assembler type in the first printed line after startup was always Z80,
regardless of actual type. Fixed, so that the first printed line now
contains correct assembler type.

2010-04-10  1.1.1

Fixed small bug in command line help and instructions. Option '-t 8051' in example, which is invalid,  changed to '-s 8051'.
