19 Aug 89 This is a revision to the earlier release to SPEEDUP which now recognizes the ZCPR 3 Extended Environment thereby permitting it to operate under NZCOM with non-standard CCP and DOS sizes. Please notify me if there are any problems so that I can correct them before releasing the source. Also in this library is LINKPRL.COM which is a simple linker to create PRL files for Type 4 modules, or to create SPEEDUP. The source will be made available as soon as the TCJ article comes out explaining it. A second part of the article will detail the inner workings of SPEEDUP. A couple of configurable items can be configured with Al's ZCNFG 1.3 or later, and the SPEEDUP.CFG is also contained herein. NOTE: This version of LINKPRL supercedes a version of 12 Aug 89 which placed the word pointer on page 0 of PRL files at the wrong address Hal Bower
