* --Aliases--
|
|
* Aliases are like shortcuts for complex functions, variable assignments,
|
|
* etc. You can use a simple alias to rename a longer command (eg 'set' for
|
|
* 'setting' for example), or concatenate more commands into one
|
|
* (eg. 'ng' for 'load %A; unpause; debug_level 5'). Aliases can parse the arguments
|
|
* given to them in the command line.
|
|
* - "%A - %Z" substitute arguments 1 t/m 26
|
|
* - "%+" lists all parameters keeping them seperated
|
|
* - "%!" also lists all parameters but presenting them to the aliased command as one argument
|
|
* - ";" allows for combining commands (see example 'ng')
