“…This places the burden of syntax analysis and a limited form of syntax error correction on SILT1, i.e., it must be ensured that syntax errors detected by SILTI in the source program do not propagate to SILT2. The syntax error recovery strategy used by SILTI is analogous to that introduced by Hartmann [4].…”

This paper describes the implementation of an extended Pascal compiler on the TI 990 minicomputer, the TI 980 minicomputer, and the IBM System 370. The compiler was designed to be as machine independent as possible; the parser and machine independent optimizer are parameterized so they are identical at the source code level for all machines. The paper describes the language modifications and extensions to Pascal, the parser, the optimizer, and the code generators. In addition, the intermediate language utilized is discussed at length.

SUlMlMARYThe process of transporting Brinch Hansen's implementation of Concurrent PASCAL to another minicomputer is described. Applicable porting strategies are discussed with emphasis on the design decisions made for a specific transportation. Important design decisions include the use of a virtual code interpreter and implementation in an operating system environment. The problems of this transportation are illustrated with accompanying suggestions for a more portable system. KEY WORDS Portability Concurrent PASCAL Kernel Interpreters MultiprogrammingOperating systems Abstract machine Address mapping computers. Per Brinch Hansen, the designer of Concurrent PASCAL, and his staff at California Institute of Technology have implemented Concurrent PASCAL on the DEC PDP-1 1.2 This implementation has been widely distributed both in a version suitable for the PDP-11 and in a version intended to be moved to other computers. The language implementation includes a compiler for Concurrent PASCAL and a compiler for Sequential PASCAL, a subset of Standard PASCAL as defined by Wirth,3 which are both written in Sequential PASCAL. The Brinch Hansen distribution system also includes an operating system (SOLO)4 which is written in Concurrent PASCAL and provides a single-user environment for the development of both Sequential and Concurrent PASCAL programs. This paper contains a summary of the porting strategy used and the experiences and insight gained during the process of moving the Brinch Hansen system to an Interdata 8/32 computer. APPROACH T O PORTABILITYSeveral techniques have been proposed or used in moving programs and/or programming systems from one computer to another.6 Among these techniques are 'standard' languages, macro implementations and abstract machine architectures. With regard to the Brinch Hansen system, two of these approaches are immediately applicable. Similar to the
