35.5 Error Messages

This module has the following error messages:

• - 2001: data size of "%d" bits is not supported
• - 2002: value does not fit into immediate. Allowed range is [-32768:32767]. Value is %i
• - 2003: destination address (immediate value) is to far away. Allowed distance/immediate value is [-32768:32767]. Actual distance/immediate value is %i
• - 2004: congratulations. Your jump distance (%i) actually goes beyond the scope of [-33,554,432:33,554,431]. We, the creators of Hans, are so proud of you for writing 33 million instructions. You should maybe take a break :D
• - 2005: immediate is %i but allowed range is %s for %s
