15.2 Flow controlling instructions
15.2.1 Jump to a block ($GOTO)
$GOTO N<expression>
$GOTO [<label>]
One of the following parameters is defined in this instruction:
This instruction provokes a jump to the block defined with
"N<expression>" or "[<label>]", that may be defined at a point before
or after the $GOTO instruction. Program execution continues after the
jump at the indicated block.
The $GOTO instruction may be programmed in two ways:
• With a block number.
In these blocks that are the target of a jump, the label must be
programmed followed by ":".
• With a label.
The call instruction and the destination block must be in the same
program or subroutine. There cannot be a jump to a subroutine or
between subroutines.
There cannot be jumps to blocks contained in another instruction ($IF,
$FOR, $WHILE, etc.)
Although the flow controlling instructions must be programmed alone
in the block, the $GOTO instruction may added to an $IF instruction
in the same block. This way, it is possible to exit the blocks contained
in an instruction ($IF, $FOR, $WHILE, etc.) without having to end the
loop.
<expression> It may be a number, parameter or arithmetic expression
whose result is a number.
<label> It may be a sequence of up to 14 characters consisting of
uppercase and lowercase letters and numbers (neither
blank spaces nor quote marks allowed).
Destination N<number>:
Call $GOTO N<number> or N<number>:
Destination [<label>]
Call $GOTO [<label>]
