[[SPSS]] macros are fundamentally a form of string manipulation. The '''SPSS macro language''' is a string manipulation and expansion facility.

Line 13: Line 13:
Arguments can be passed into a macro. Be mindful that they will first be tokenized before being exposed to the macro expansion. {{{
define !HelloWorld()
  string HelloWorld (A13).
  compute HelloWorld="Hello, World!".
  list HelloWorld.
enddefine.
}}}

||`!tokens(N)` ||Consume N tokens ||
||`!charend('C')` ||Consume all tokens until C ||
||`!enclose('S','E')`||Consume all tokens starting from S until E ||
||`!cmdend` ||Consume all tokens until the end of the command||		 ----

=== Named Arguments === == Language ==
Line 25: Line 27:
Tokens can be set into named arguments using a `key = function` pattern.

{{{
define !generate(var1=!tokens(1)
                /var2=!tokens(1))
  compute !var1=0.
  compute !var2=0.
!enddefine.

!generate var1=foo var2=bar.
!generate var2=bar var1=foo.
}}}

Note that the arguments are accessed in the program by prepending the name with an exclamation mark (`!`).

Also note that arguments can be specified in any order.



=== Positional Arguments ===

Tokens can also be set into positional indices (`!1`, `!2`, and so on) using the `!POSITIONAL` keyword.

{{{
define !generate(!positional !tokens(1)
                /!positional !tokens(1))
  compute !1=0.
  compute !2=0.
!enddefine.

!generate foo bar.
}}}

All positional arguments can be accessed as a blank-delimited string with `!*`.		  * [[SPSS/Macro/Arguments|Macro Arguments]]
