tcl.list-locks_rp

Verb: Access/TCL, Releases: AP

Displays status of all locks.

Syntax

list-locks {(options)}

Description

displays the current status of all Pick/BASIC execution locks, item locks and group locks.

'Basic' Locks are the 64 Pick/BASIC program execution locks (used by the 'lock' statement in Pick/BASIC programs).:

00 This lock position is unused.
nn The port.number using this lock position.

The 'Basic' locks are arranged in four line of 16 columns each. Position 1 on the first line represents lock 0, position 2 is lock 1, and so on. (Since each position is represented with zeros by default, it's difficult to tell if port zero has a lock set.)

Options

fid Displays item-lock status for the group starting at the specified frame-id (fid). (R83 only).

i Displays item-locks only.

p Directs output to system printer, via the Spooler.
