For global locks, enter one space before the '^'.` DESCRIPTION: `Enter the locked data structure as set in the LOCK command, except:` `1) If the lock is on a global data structure, enter a space before` `the '^'.` `2) If an array subscript is a variable, enter a legal variable name.` `In examples 2-4, note that a space is necessary before the '^' of the global reference.` `Example 1:` `If the lock is on the local variable 'DPT', enter 'DPT'.` `Example 2:` `If the lock is on the entire ^DPT global, enter ' ^DPT'.` `Example 3:` `If the lock is on the 0 node of a record in the patient file then the` `record number must be represented by a variable. Select a variable,` `lets say DFN. So if the lock is on '^DPT(,0)',` `the lock template may be entered as ' ^DPT(DFN,0)'.` `Example 4:` `The same as example 3, except that the ""POV"" node is locked.
