Glink: API reference manual Gallagher & Robertson
Unlike a normal link, this one does not deliver
advisements when the data has changed but simply
whenever there is any data to deliver. We recom-
mend that for secure delivery of data, you define a
warm link to the LinDat item rather than the
LinGet item, and issue requests on LinGet when
the advisement for LinDat is received.
LinProc max_length Same as LinGet, except that when the data is col-
lected it will also be processed by the emulator (i.e.
displayed on the emulator screen).
LinSts Returns the current connection state of the line. If the
emulator is connected '1' is returned, otherwise '0'.
ScrGet Returns the current script parameter value if any (if a
script is running). The value returned with this com-
mand is the same as is set by the script PARAM com-
mand and a warm/hot link to the script parameter
may be used to monitor the current status of a script
that may have been initiated via the DDE. Note that
if the script terminates then the script parameter no
longer has a defined value - in such cases, you
should use the ScrGget request. You may set the
value of the script parameter from your DDE
application by using the ScrPut poke.
ScrGget Returns the current global script parameter value.
This may be set in the script using the GPARAM com-
mand and you may therefore use this with a
warm/hot link to return a status from the script being
executed (in this case ScrGet will not work in that
the script parameter disappears once the script has
terminated). You may set the value of the global
script parameter from your DDE application using
the ScrGput poke.
StxGet This request returns the current start of text position
as an ASCII string 'X Y'. If no start of text
position is defined then zero will be returned for the
Y position and the X value is undefined.
