I think any manual (including IBM Principle of operations) would contain the details.
A re-entrant module is one which does not have self-modifying property. In other words, the code must not change itself and any data that must be modified must reside outside of the module. For example, if you wish to modify a working storage, it must be acquired from and handled outside your module.
However, you are free to change the values in any location outside your module eg. registers, external storage devices. |
