PQ-SELECT (Proc) (m618404+pqselect.htm)
Executed from a Proc, loads a list of item-ids into a select register.
PQ-SELECT register-number
register-number is the number of the select register (1 to 47) in which the item-ids are to be placed.
To process a selected list generated within a Proc, PQ-SELECT must be placed in the stack.
The item list processed by PQ-SELECT can be obtained as the result of the execution of a SELECT command, or of any other TCL (or English) command that generates an active list. Refer to Select Registers for a complete list of commands that generate an active list.
Item-ids are referenced one at a time, using a !n direct or indirect reference.
This command cannot be executed directly at TCL.
An example showing the use of PQ-SELECT in conjunction with the Proc command IF S is included in the description of that command.

This example selects all the items in the BLOCK-CONVERT file, loads the item-list into select register 1 and displays them one at a time.
