Using the Starburst vs 7 segment display

[myekelgreene]

I have a question. Why is the format for using the Starburst to display a character ,has to be within apostrophes , but the 7 segment doesn't.
Where can I find more or better information on the use of this and other commands? The wiki wasn't as clear as it could be.

Hello,

A single character in apostrophes allows us to speficy an ASCII value.

so for example 'a' would pass the decimal value 97.

This table might help.

The 7-seg is likely printing a decimal number rather than an ASCII character.

This is very good information to have. I am surprised that it isn't presented in the description with the starburst.
Thank you.
