Use this environment to load strings into the memory registers at startup.
The format is
\registers{ <1st register name> = {<string>} <2nd register name> = {<string>} . . <last register name> = {<string>} }
The permissible register names are `0' through `9' and `A' through `Z'. All strings must be balanced in terms of braces, and not longer than 255 characters. The `=' is optional. The register strings may lie on several lines.
