    CHSET ÆHELPÅ

    Explanation:

    CHSET is a utility that allows you to make changes in the command
    header  of a command file with a  .CMD filetype.  CHSET has three 
    fields that you can display or change, corresponding to the three 
    fields that CHSET modifies in a command header.  The three fields 
    and their possible settings are:
 
    8087 - The  8087  field  has three possible settings, ON, OFF, or
    OPT  (optional).   Specify  ON  for programs that require an 8087 
    processor  in  order  to run.  Choose OPT when you have a program 
    that  can use an 8087 if it is present in your system, or emulate 
    an  8087 if it is not present.  Specify OFF if you want to cancel 
    a previous ON or OPT selection.

    SHARED - The SHARED field has two settings, ON or OFF.  Select ON 
    when  you  want  to modify a program's command header so that the 
    program  can  use  Concurrent  CP/M's  shared  code capabilities.  
    Specify OFF if you want to cancel a previous ON selection.

    SUSPEND - The SUSPEND field has two options, ON or OFF.  When you 
    select  ON,  CHSET  modifies  a  program's command header so that 
    Concurrent  CP/M  suspends  that   program's  operation  when  it 
    occupies a  switched-out virtual console.  OFF cancels a previous 
    ON selection.

    Changing Field Settings

    You  can  change any or all of CHSET's fields in a single command
    line.  To  change  a setting for a field or fields, enter a CHSET 
    command  with  a filespec and the fields you want to change.  For 
    example, if you type

    B>chset calc.cmd Æ8087=opt,shared=on,suspend=onÅ

    CHSET  modifies  the command header of a program contained in the 
    file CALC.CMD.  

    Displaying Field Settings

    When  you  enter  a  CHSET  command  with a filespec and no field 
    settings,  CHSET  displays the settings for the specified file or 
    files.  For example, if you type

    B>chset erase.cmd

    CHSET responds with the following display:

    B:ERASE   .CMD settings are Æ8087=OFF,SHARED=OFF,SUSPEND=OFFÅ

    Modifying  a command header is not a trivial matter.  While CHSET
    cannot  harm  your  .CMD files, inappropriate use of it can cause 
    your programs to behave in unpredictable ways.
