QMESH/RHENUM/QPLOT mainframe and plotter conversion: CDC6600 to IBM 360/370 and SC4020 to Calcomp. [In FORTRAN]
A code conversion project to modify an existing set of FORTRAN computer programs to run on a different mainframe and to drive a different plotter is discussed. The mainframe conversion was from a CDC6600 to an IBM360; the plotter conversion was from an SC4020 (driven by calls to SCORS library subroutines) to a Calcomp. The changes made because of differences between the FORTRAN compliers were relatively minor. IBM ASSEMBLER source decks were acquired to replace all of the CDC special features (such as ENCODE/DECODE) which have no direct IBM equivalents. The plotter call conversion was more difficult, but was still relatively straightforward. By far the most difficult part of the conversion effort involved converting the file-handling protocol from default-tolerant SCOPE on the CDC6600 to explicit JCL (Job Control Language) on the IBM360; listings of all the IBM deck setups used are included in the Appendix. The programs converted were QMESH, RENUM, QPLOT, RENUM8, and QPLOT8, which together constitute a general-purpose quadrilateral-element mesh generation preprocessor to a variety of finite-element stress analysis programs. 7 figs., 2 tables.
