Radio Shack TRS-80 PC-3

(A * B)A2
A (2, 3) +A (3, 4) +5.0 - C
(A/B) *(C + 0)
In certain circumstances the multiplication operator can be implied:
2A
7C
ABC
is the same as
is the same as
is the same as
As you can see from the last example, there is a possibility that implied multiplication could be confused with other BASIC words,
so don't use this form unless the context is very clear.
NOTE: Negative numbers may not be raised to a power with the A operator since you may obtain incorrect signs. If negative
numbers are encountered in a program, convert the numbers to positive numbers using ABS before using the A operator.
You will then have to change the result to the appropriate sign.
String Expressions
String expressions are similar to numeric expressions except that there is only one string operator -- concatenation (+). This is
the same symbol used for plus. When use with a pair of strings, the + attaches the second string to the end of the first string and
makes one longer string. You should take care in making more complex string concatenations and other string operations because
the work space used by the PC-3 for string calculations is limited to only 79 characters.
NOTE: String quantities and numeric quantities cannot be combined in the same expression unless one uses one of the functions
which convert a string value into a numeric value or vice versa.
