#DEFINE

Purpose:

Defines a macro.

#DEFINE name(arg1, arg2, ..., argN) formula

name	-	A string up to 15 characters, the name of the macro.
argN	-	Optional. Zero or more arguments to pass to the macro expression.
formula	-	The macro expansion incorporating those arguments and evaluating to a real, string, series, or table.

#define autocor(s) conv(s, reverse(s))/(2*sersize(s))

defines a macro which performs an auto-correlation of a series.

W1: gsin(128, 1/128, 4.0)

autocor(W1)

calculates the auto-correlation of the sine wave.

#DEFINE can redefine existing macros.

Macros are defined and saved with the Worksheet. Use MACWRITE to write macros to a file.

See DEFMACRO to dynamically define a macro within an SPL routine.

The maximum length of a macro name is 63 characters.
