Labels of transition.
______________________

    The labels of transition are applied to the instruction of index points
of sites of the code, used by commands of transition of the built-in
assembler and operators goto/GOTO.

    There are two such as labels of transition: global and local. Global
labels, as follows from the name, - label, which are visible from any place
in program. The local labels are visible only within the limits of procedural
block, also are not defined for it by bounds.

    The labels are defined by the identifier terminating in a colon. If
identifier contains even one character of lower case letters (characters of
lower the register, small characters), it - global label of transition, in,
opposite, case it - local label of transition.

    The global labels of transition should not be used inside dynamic
procedures; there it is possible to use only local labels. It is important
for remembering, as, because of application of such tool as the macros,
dynamic procedure can be present at several places of the code, that will be
mean, that to a label corresponds more than one address.

    The labels outside of procedures actually settle down in the field of
data of the program. If the data and code are in one segment (namely so sets
the program written on C--), the labels outside of procedures become simplis
and effective method for obtaining distances between parts of the program. In
quality of names for labels outside of procedures can be used unique it is
possible to use identifiers, in which large, small and mixture large and
small characters.
