Controls Functions

---

The control functions let you set global parameters and permissions that affect all or selected sections of the technology file.

The techParams control lets you set parameters that you can use in the other technology file sections. The function techSetEvaluate lets you specify whether or not to evaluate parameters when you use techGet functions or dump the technology file. By default, no evaluation is done.

The techPermissions control lets you set read-only and read/write permissions on sections of your technology file for different system users. Users can then access technology file sections only as their assigned permissions allow.

In the following example, techGetSpacingRule returns the value of the control parameter when techSetEvaluate is set with the default t value. After you set the evaluation flag to nil, techGetSpacingRule returns the unevaluated value for the minWidth spacing rule.
