(6) Online programming is possible
By connecting the QD51 (-R24) to a PC/AT personal computer and carrying out
settings at a console, a BASIC program can be edited and debugged.

(7) Multitask debugging is possible
By connecting the QD51 (-R24) to a PC/AT personal computer and setting a
debugger, debugging can be performed while performing multitask processing.

Multitask debugging is performed by inputting the Debug command from the
debugger. By executing the Debug command, the following can be done.
• The BASIC program for the specified task No. area can be run and terminated.
• The variable values specified in the BASIC program for the specified task No.
area can be read and written.
• Data can be read from and written to the QD51 (-R24)'s internal memory.
• Common events and message port use status displays, etc. can be shared
between BASIC programs.
(8) Both interpreter BASIC and compiled BASIC can be used
By compiling a BASIC program created in interpreter BASIC with the BASIC
compiler, the BASIC processing speed can be markedly increased.
Interpreter BASIC : BASIC in an execution format where the QD51 (-R24)
Compiled BASIC : BASIC in the format where the program is compiled (the

when the program is completed and the QD51 (-R24) runs it
in machine language directly.
