1 ==========

1 A "label" is written as a symbol immediately followed by a colon ':'.
1 The symbol then represents the current value of the active location
1 counter, and is, for example, a suitable instruction operand.  You are
1 warned if you use the same symbol to represent two different locations:
1 the first definition overrides any other definitions.

1    On the HPPA, the usual form for a label need not be immediately
1 followed by a colon, but instead must start in column zero.  Only one
1 label may be defined on a single line.  To work around this, the HPPA
1 version of 'as' also provides a special directive '.label' for defining
1 labels more flexibly.
