Limits
Set Limits [ option value ] ...
Sys OFF
Run OFF
Colonreq OFF
Hold n
Proc x
(Initially: Sys ON, Run ON, Colon OFF, Hold 10, Proc 4)
Set Limits Sys Off disables the execution of shell commands from within Qedit. It also prevents Qedit for Windows users from accessing host commands.
Qedit normally accepts shell commands with or without a prefix (colon or exclamation mark). To enforce the use of a prefix for shell commands, use Set Limits Colonreq ON.
These are one-way options -- once disabled, they cannot be enabled again by the user.
The rest of the options do not apply to Qedit/UX. They are still accepted for compatibility with the MPE version of Qedit.
