ALTER
operations to its destination in a single I/O operation. It still appears to the user
that each single operation is a discrete operation.
•
When the REFRESH operation is enabled, and the function keys F1 and F2
are used to switch terminal pages, all REFRESH I/O operations are
automatically piggybacked onto the same input-output operation as the select
terminal page operation. This process ensures that what you see reflects the
current state of the message cache and eliminates a subsequent update a few
seconds later. If this piggyback operation is not performed, the adaptive refresh
algorithm determines that the screen data is out of sync with the message
cache and that the program has to do another update a few seconds later.
•
Setting REFRESH to zero disables the REFRESH option completely.
RETAIN ON | OFF
specifies whether the first declaration of a ?SECTION is to delete all existing user
string and integer variables.
ALTER RETAIN OFF causes the deletion of the existing user string and integer
variables and is the default.
If you are using the INVOKE filename statement in menu productions, set
ALTER RETAIN ON to retain variables across multiple script invocations.
The standard SeeShell sets the ALTER RETAIN option to ON.
SECTIONDELAY seconds
specifies the number of seconds that the SeeView program waits between sections
when executing the current shell. During this pause, the section name just
executed appears on line 25 of the terminal. Once the delay is completed, the next
sequential section in the shell file is executed.
The default is SECTIONDELAY 1, but the standard SeeShell sets
SECTIONDELAY to 0.
SECTIONMSG ON | OFF
specifies whether a timer countdown message is displayed while the SeeView
program is waiting for the time interval defined by SECTIONDELAY seconds to
process the next sequential section in the shell file.
The default is OFF.
SETMODE110 ON | OFF
causes an immediate SETMODE 110 ON|OFF operation. Setting SETMODE110
permits the logical editing of alternate character data.
OFF indicates that alternate characters are delimited with shift-out and shift-in
ASCII control characters. SETMODE110 ON indicates that alternate characters are
delimited with the high-order bit of each character byte set on.
