Why does Quartus II not have get_all_location_assignments collection in tcl?

[Altera_Forum]

The set_location_assignment is used to set a port on the design to connect to a pin on the FPGA. I doubt this has any other applications. 

How do I get a collection of all the pin location assignments and print them to a file since a collection cannot be obtained using the expected way. How does one use tcl to remove all pin assignments in the pin planner so we can start over again?

Assignmnet Editor has a Filter to show Location assignments only. Sort/delete/disable from there is what I usually do. (It can also be done in Tcl if you really want to do that, but the AE has always been so easy)

i think because it caught by some virus, maybe just try , just copy the code below for tcl 

 "tcl 1 : command : please remove all pins : remove: remove it"

The purpose here is to learn more about tcl and less about how to assign/remove pin assignments. 

 By the way newzealand, I do know enough tcl to know that your tcl has syntax errors in it.
