This package is a revision to the package submitted at Chicago last spring. There are 6 changes. 1. a bug in the cross hair cursor support has been eliminated. 2. a bug in SCALE.MAC which caused an occasional floating point to interger overflow error has been eliminated. 3. to run under RT-11 you should just assemble all the *.MAC'S 4. there is a conditional assembly statement to change in PLOTPRIMS.MAC and PLTDAT.MAC to allow the package to support a Tektronix 4025 (the user program must call TK4025) 5. for users in an overlayed enviroment only PLTDAT.OBJ needs to be in the root. 6. a bug in the call to 'HOME' has been fixed to allow it to work on all terminal types. All the fortran programs on the tape except TK4025 are demonstration programs that should be compiled and linked to the library before you try to use them. SFGL70 is a graphics package which supports Tektronix 4006,4010,4014 AND 4025 terminals. It's useful feature is that in most cases it will only add approximately 1K words to the user task. When using the file SFGL70.DOC to learn how to use the package, ignore the references to PDP-6 equivalent. They were needed internally at UTRC because this package replaced an older graphics package our users had been using. This file explains the SFGL70 package submitted to the 1980 FALL DECUS Symposium by Ken Demers. If you encounter any problems or have any questions please call me at United Technologies Research Center East Hartford, Connecticut (203) 727-7527. The package can run under IAS and RSX-11M. I also have a version that can be conditionally assembled for RT-11(not on this tape). SFGL70.OLB is the library to be linked with the user task. The distributed version has been built with IAS. To run under RSX-11M assessmble to source modules and create a library from the object modules. The user manual is in RUNNOFF format in the files SFGL70.RNO and SFGL70.DOC. I origionally received the PLOTPRIMS.MAC routine from Steve Davis of Haskins Labs New Haven, Ct. It was origionally developed at the Speech Communications Research Lab Inc. Santa Barbara, Ca. However I have made various changes to enhance the total package which I developed. One last comment: Many people around the USA are currently using the package and find it very useful. The package will work on a VT100 (if it has the hardware to make it look like a Tektronix 4010). There will be future enhancements to take full advantage of the VT100's additional capability. Thanks, Ken
