To prevent translation of alphabetic characters in
a program to uppercase,
simply enclose the characters in single or double quotation marks.
The language processor does not change numbers and special characters,
regardless of whether they are in quotation marks. Suppose you use
a SAY instruction with a phrase containing a mixture of alphabetic
characters, numbers, and special characters; the language processor
changes only the alphabetic characters.
SAY The bill for lunch comes to £123.51!
results in:
THE BILL FOR LUNCH COMES TO £123.51!
(This
example assumes none of the words are the names of variables that
have been assigned other values.)
