STR / NUM / CMD

The STR, NUM, CMD commands are very similar to each other, including having the same storage space. The number inside curly brackets indicates the index. This marks the position of STR/NUM/CMD. It can be configured in the Setup/Other menu how many of them can exist, min:30, max:500, default:50. RAM is limited, so use it wisely.
