### Parameters

Parameters specify the arguments required by the command. The format of a command line is:

    nM><command> <parameter1> ... <parameterN>

Commas or blanks separate arguments from each other and from the command name. Parameter names are identified and given default values in the NeXtMidas command dictionary; if listed in the dictionary, the parameter name may be abbreviated. To see the arguments for a particular command, use `EXPLAIN`. Below is an annotated example of the explanation for `RAMP.` It shows that the `RAMP` command has 8 arguments indicated within the <angle brackets>:

    nM> explain ramp
    RAMP  creates a ramp (sawtooth) file

    <OUT>       Nameof output file
    <FORM>      Formatof output file (SF< CF<SB< etc.)
    <ELEM>      Numberof elements in output file
    <DATASTART> Ordinatevalue for first point in file
    <DATAINC>   Ordinatedifference between consecutive points in file
    <START>     Abscissastart
    <DELTA>     Abscissadelta
    <UNITS>     Abscissaunits

To see the defaults of a command, type `DEFAULT` before the command name. The example below shows the defaults for `RAMP:`

    nM> default ramp
    INFO:RMP;SYS:2,P,8,OUT=,FORM=SF,ELEM-4K,DATASTART=0,
    DATAINC=1,START=0,DELTA=1,UNITS=1
    nM>

There are two types of parameters: Positional and Keyword.
