AppendixA ktl - built-in command providing access to KTL keyword libraries

A.2 Description

This command provides access to KTL keyword libraries. option identifies the operation (many of the options have the same names as user-callable KTL routines). Depending on option, name is either a service or a keyword name.

Valid options, which cannot currently be abbreviated, are:
Options to the ktl command
Name Description
open open a connection to a KTL service (c.f. ktl_open())
link link a (service,keyword) pair, giving it a name used in subsequent operations
monitor enable a monitor on keyword change, optionally executing a Tcl script (c.f. ktl_read(KTL_CONTINUOUS)) (ktk only)
read read the value of a keyword (c.f. ktl_read())
write write the value of a keyword (c.f. ktl_write())
ioctl return information about a keyword

Options to the `ktl` command
Name	Description
`open`	open a connection to a KTL service (c.f. `ktl_open()`)
`link`	link a (service,keyword) pair, giving it a name used in subsequent operations
`monitor`	enable a monitor on keyword change, optionally executing a Tcl script (c.f. `ktl_read(KTL_CONTINUOUS)`) (`ktk` only)
`read`	read the value of a keyword (c.f. `ktl_read()`)
`write`	write the value of a keyword (c.f. `ktl_write()`)
`ioctl`	return information about a keyword

The obvious close, unlink and unmonitor have not yet been implemented.
