How to resolve the algorithm Named parameters step by step in the J programming language

Problem Statement

Create a function which takes in a number of arguments which are specified by name rather than (necessarily) position, and show how to call the function. If the language supports reordering the arguments or optionally omitting some of them, note this. Note: See also:

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Named parameters step by step in the J programming language

Source code in the j programming language

NB.  Strand notation
myFunc['c:\file.txt'  906  'blue' fs]

NB.  Commas, like other langs
myFunc['c:\file.txt', 906, 'blue' fs]

NB.  Unspecified args are defaulted ("optional")
myFunc['c:\file.txt' fs]

NB.  Can use named arguments, like eg VB
myFunc[color='blue'  fs]

NB.  Often values needn't be quoted
myFunc[color= blue   fs]

NB.  Combination of comma syntax and name=value
myFunc[max=906, color=blue fs]

NB.  Spelling of names is flexible
myFunc[MAX=906, COLOR=blue fs]

NB.  Order of names is flexible
myFunc[COLOR=blue, MAX=906  fs]

NB.  Even the delimiters are flexible...
myFunc<MAX=906, COLOR=blue fs>
