Once blocks are defined, special instructions can be used in them. The instructions called EXIT and UP allow
jumping to the end or to the beginning of a block.
These instructions
{
}
Note: in Saturn mode do not make confusion between EXIT and UP instructions, which are GOTOs, and EXIT
and UP after a test, which are GOYES's. EXIT and UP can jump to the beginning or to the end of an upper-level
block by specifying the number of blocks to exit, after the UP or EXIT instructions.
Note 1: EXIT1 is equivalent to EXIT, and UP1 is equivalent to UP.
Note 2: the same rules apply in ARM mode: EXITGE3 for example is a BGE for the exit label 3 blocks down
, and can be nested within another block.
