See the following illustration for an example of unconditional jumps:
11.15.2
Conditional program jumps
Functionality
Jump conditions
are formulated after the
IF instruction
. If the jump condition (
value not zero
) is satisfied, the jump takes
place.
The jump destination can be a block with a
label
or with a
block number
. This block must be located within the program.
Conditional jump instructions require a separate block. Several conditional jump instructions can be located in the same
block.
By using conditional program jumps, you can also considerably shorten the program, if necessary.
Programming
IF condition GOTOF label
;Jump forward
IF condition GOTOB label
;Jump backwards
GOTOF
;Jump direction forward (in the direction of the last block of the pr
ogram)
GOTOB
;Jump direction backwards (in the direction of the first block of the program)
Label
;Selected string for the label (jump label) or block number
IF
;Introduction of the jump condition
Condition
;Arithmetic parameter, arithmetic expression for formulating the condit
ion
Comparison operations
Operators
Meaning
= =
Equal to
< >
Not equal to
>
greater than
<
less than
> =
greater than or equal to
< =
less than or equal to
The comparison operations support formulating of a jump condition. Arithmetic expressions can also be compared.
The result of comparison operations is "satisfied" or "not satisfied." "Not satisfied" sets the value to zero.
