Subject: Another question regarding record stringout, lso and Record reference manual in general

Hi,

I can't find a description in the Record Reference Manual of what ‘DCT’ means.
This is always displayed in the tables:

Stringout Record:

Field Summary Type DCT Default Read Write CA PP
VAL Current Value STRING [40] Yes  Yes Yes Yes
DOL Desired Output Link INLINK Yes  Yes Yes No
OMSL Output Mode Select MENU (menuOmsl) Yes  Yes Yes No


lso record:

Field Summary Type DCT Default Read Write CA PP
VAL Current Value STRING or CHAR[SIZV] No  Yes Yes Yes
SIZV Size of buffers USHORT Yes 41 Yes No No
DOL Desired Output Link INLINK Yes  Yes Yes No
OMSL Output Mode Select MENU (menuOmsl) Yes  Yes Yes No


I'm completely confused about the description of the records. That's probably because we've been trying all afternoon.

E.g. stringout :

"The first field that determines where the desired output originates is the output mode select (OMSL) field, which can have two possible value: closed_loop or supervisory. If supervisory is specified, DOL is ignored, the current value of VAL is written, “

"DOL can also be a constant, in which case VAL will be initialized to the constant value. “
"Note that if DOL is a constant, OMSL cannot be closed_loop.”

???

Similiar confusion with lso:

"If supervisory is specified, DOL is ignored, "
"DOL can also be a constant instead of a link, in which case VAL is initialized to the constant value. “
