A screen painter originally released as "Panel" for CP/M in 1981 and then put out PL/I code targeting the Digital Research PL/I compiler. Later converted to having a C output and ported to DOS and re-released with a v1 version number in or around 1985, and in 1988 as Panel Pus II as a screen painter and C UI library with support for OS/2 and VAX VMS and the possibility of a DLL version on OS/2 and DOS which opened up support for FORTRAN as well as C on those two operating systems, the company shortly after that added support for UNIX, Xenix and QNX.

By the time version 2.1 hit the market in 1991 the library not only supported the usual multiple windows and menu options but had added features such as field editing capabilities that include automatic conversion of currency and date formats to different national standards and full word-wrap text editing.

The system is still being sold in 2016, albeit without any form of support but with full source code.

Lattice version

The Lattice company sold a version of Panel under its own name in the mid/late 80's, this version targeted the Lattice C compiler and environment specifically and therefore systems that the Lattice C supported but RCS did not including the Atari ST and the Amiga. In other terms the Lattice version appears identical to the RCS version and shipped with the same manual as the RCS Panel DOS version. After the introduction of Panel Plus the RSC company offered a Lattice version of that program separately form other versions at a discounted price.
