F l a g s
Some flags may be used to enable/disable MicroLYNX functions. Other flags
may be used to indicate system or program status. Flags may be either TRUE (1)
or FALSE (0).
1]
Factory-defined.
2]
User-defined.
3]
Special User-defined.
F a c t o r y
These flags are pre-defined at the factory and cannot be deleted. When an IP
(
Initialize Parameters
) instruction is given, these flags will be set to their factory
default state. There are two types of factory-defined flags: Read/Writable and
Read Only.
U s e r
One of the powerful features of the LYNX instruction set is that it allows the
user to define flags both inside a program (local) or outside a program (global).
User-defined flags are deleted by means of the DVF (
Delete Variables and Flags
)
instruction.
U s a g e o f F l a g s
Flags are typically used to set conditions for branches and subroutine calls. They
are also useful for program debugging. For the definition of all the factory-
defined flags, see the LYNX Product Family Manual on the CD.
K e y w o r d s
Keywords are used in conjunction with the PRINT, GET and IP instructions to
determine what sub-set of the VAR/FLG/IOS will be acted upon by the instruc-
tion used. The keywords are:
ALL:
Include all variables, flags and I/O states.
VARS:
Include only variables.
FLAGS:
Include only flags.
UVARS:
Include only user-defined variables.
UFLGS:
Include only user-defined flags.
IOS:
Include only I/O line states.
STATS:
Include only factory-defined status flags.
