Maybe a Bug in mdk-1.3.0

[sqc]

Hi,


It seems that there is a bug in the MDK 1.3.0. 


The command 'pline' cannot be used. When I type 'pline [some number]', the 
error message is given. It says that this is not a valid command.


But I find that there is handler for the command 'pline'. So, I check the 
source. And I find that the command 'sbt' has not conrresponding enumeration 
definition in 'mix_vm_command_t'.
By inserting a temperary enumeration for the command 'sbt', the problem can be 
solved. The command 'pline' can be used.


BTW, I like the MDK very much. It makes me study the TAOCP easily. 


Best regards,
Kevin Sun
