Parameter formats

There are three parameter formats.
Which format can be used depends on the TTL command, So please check the command reference.

1) Positional parameter

Specify the parameters in order.
Parameters not explicitly listed as "Keyword parameter" in the command reference are "Positional parameter".

例:
  ttlcommand 10 20
  1st : width
  2nd : height

2) Keyword parameter

Passing keyword/value pairs as parameter.
Parameter can be passed in any order.

例:
  ttlcommand 'width=10' 'height=20'
  width keyword  : width
  height keyword : height

3) Positional parameter + Keyword parameter

The first few are "Positional parameter", the rest are "Keyword parameter".
"Positional parameter" order is fixed, "Keyword parameter" is in no particular order.

例:
  ttlcommand 'Terminal' 'green' 'width=10' 'height=20'
  1st            : font
  2nd            : color
  width keyword  : width
  height keyword : height

Background

"Keyword parameters" was introduced in Tera Term version 5.3 when the listbox command enhance to pass many parameters, and besides, to minimize the number of parameters to be specified.
