- * Revision 37.9 93/06/20 18:52:28 Torsten
- * Now does its own buffering (32k) in order to speed things up.
- * The effect is quite impressive :-)
- *
- * Revision 37.8 93/03/01 12:49:37 Torsten
- * Changed all occurrences of "struct DosBase *" to "struct DosLibrary *"
- *
- * Revision 37.7 93/02/22 18:15:07 Torsten
- * Changed to be linked with the support library
- *
- * Revision 37.6 93/02/19 18:04:51 Torsten
- * Fixed minor bug in the return code check in entrypoint().
- *
- * Revision 37.5 93/02/19 02:53:58 Torsten
- * Major rewrite; totally restructured the code.
- *
- * Revision 37.4 93/02/12 13:19:15 Torsten
- * Moved the source to RCS.
- * Reformatted source.
- * Replaced exec.library/SetSignal() with dos.library/CheckSignal().
