Note that "-" in -B is the negative sign and "-" in 0-B represents
subtraction.
Multiplies X by Y and substritutes the result in to variable A.
Divides X by Y and substitutes the result into variable A.
Adds X and Y and substitutes the result into variable A.
Subtracts X from Y and substitutes the result into variable A.
If the value of variable A is equal to X , the statement following
THEN is executed.
If the content o f variable A$ is "XYZ" , the statement following
THEN is executed.
If the value of variable A is not equal to X, the statement following
THEN is executed.
If the value of variable A is greater than or equal to X, the state­
ment following THEN is executed.
If the value of variable A is less than or equal to X, the statement
following THEN is executed.
If the value of variable A is greater than X and the value of variable
B is greater than Y, the statement following THEN is executed.
If the value of variable A is greater than X or the value of variable
B is greater than the value of Y, the statement following to THEN
is executed.
