From this table:

1)	The ASCII code (in decimal base 10) for BEL is 7.
2)	The ASCII code (in decimal base 10) for the letter 'a' is 97.
3)	The ASCII code (in decimal base 10) for the letter 'A' is 65.  It is lower than the ASCII code for the lower case letter 'a'.

5.2
To make a lower case letter upper case, subtract 32 from the lower case  letter's ASCII value.  To go the other way, add 32 to the upper case lett'ers ASCII value.
