NeXtMidas User's Guide: Function Invocation

Function Invocation and In-Line Functions

In-Line Functions

In some cases it is possible to invoke a NeXtMidas command, most importantly CALCULATOR, using function-like syntax on the command line of a different operation. The following words are reserved to allow the in-lining:

CALC - To perform complex mathematical functions.
FILE - To open, operate on, and close a file.
SEDIT - For string operations.
TEST - For logical tests

For example,

  nM>res x CALC(1,2,*)

Sets the result x to 2.

Function Invocation

See the INVOKE command to learn how to call commands NOT IN THE NEXTMIDAS COMMAND DICTIONARY from the macro language. For example,

  nM>invoke D:pi java.lang.Math.pi
  nM>invoke D:dval java.lang.Math.sin(pi)

gets pi and calls the static function sin in the Java Math class and returns the output into the result DVAL.
