- Installation
-
- Copy the diskette contents onto your hard disk:
-
- c: Change to hard disk drive c
- xcopy a:*.* j\ /s Copy from diskette drive a to directory j
-
- Then execute
-
- cd \j Hardware floating point
- copy j387.le j.le
- copy jserv387.exe jserv.exe
- or
- cd \j Emulated floating point
- copy jemu.le j.le
- copy jservemu.exe jserv.exe
-
- depending on whether your machine supports the floating point
- instruction set (80387 processor or 80486 CPU). Your PC may
- use different letters for the diskette drive and the hard disk drive.
- Substitute for a: and c: as appropriate.
-
-
- DOS Start-Up
-
- Type cd c:\j to change to the j directory, then type j to start J.
- In the J session, press F1 for help. Enter Control-D to terminate
- the session.
-
-
- Windows Installation and Start-Up
-
- Add J to the Program Manager:
-
- . click a Program Manager group window
- . select File from the menu, then select New
- . select Program Item in the dialog box and click OK
- . type J under Description
- . type c:\j\jwin.exe under Command Line
- . type c:\j under Directory
- . click OK
-
- Start J by double clicking the J icon.
-
- The J window is resizable and scrollable. It is divided into
- input and output areas containing separate logs. Press tab to
- switch between these areas, and the arrow keys to scroll the logs.
- Press F1 for help. Enter Control-D to terminate the session.
- The phrase 11!:0 'pc abc; pshow;' creates a window through the
- Window Driver interface. The facility is documented in the
- online help.
-
-
- DOS4GW DOS Extender
-
- J runs in 32 bit protected mode under DOS4GW. DOS4GW is the version
- of Rational Systems, Inc. DOS4G product that is distributed with
- the WATCOM product WATCOM C/386. DOS4GW is documented in dos4gw.doc.
- The simplified description here is adequate for most requirements.
-
- The DOS4GW command line is the program to run and its start-up
- parameters. For example,
-
- dos4gw jemu.le
-
- runs the linear executable file jemu.le.
-
- DOS4GW parameters are in environment variables dos4g, dos16m, and
- dos4gvm. The DOS set command defines environment variables.
- The sets can be entered at the DOS prompt, in autoexec.bat, or
- in a BAT file you create for the purpose of running J.
-
- . Reserve Extended Memory for Others
-
- DOS4GW running directly under DOS (not under Windows) takes all
- extended memory. If programs run from J require extended memory
- you must tell DOS4GW to limit itself.
-
- set dos16m=:2048
-
- specifies that DOS4GW should use 2 megabytes of extended memory.
-
- . Virtual Memory
-
- The DOS4GW Virtual Memory Manager provides virtual memory with
- a swap file. VMM works only directly under DOS; hosts like
- Windows provide their own virtual memory. Note: Windows virtual
- memory performs badly and should be avoided.
-
- VMM can reasonably provide up to 1 megabyte additional memory.
- Above that most applications bog down in disk thrashing. A few
- applications are well suited to virtual memory and run well with
- a workspace much larger than allowed by real memory.
-
- VMM parameters are documented in dos4gw.doc.
-
- set dos4gvm=virtualsize#2048 swapname#c:\j.swp
-
- creates/uses c:j.swp as a swap file to provide a 2 megabyte
- virtual memory space.
