&SYSECT System Variable Symbol
depends on the control section in force inside the outer macro when the inner
macro is called.
Notes:
1. The control section whose name is assigned to &SYSECT can be defined by a
program sectioning statement. This can be a START, CSECT, RSECT,
DSECT, or COM statement.
2. The value of the type attribute of &SYSECT (T'&SYSECT) is always U.
3. The value of the count attribute (K'&SYSECT) is equal to the number of
characters assigned as a value to &SYSECT.
4. Throughout the use of a macro definition, the value of &SYSECT is considered
a constant, independent of any program sectioning statements or inner macro
instructions in that definition.
