PARSE Statement

parses matrix elements as statements

PARSE matrices <(matrix-names)>;

The inputs to the PARSE statement are as follows:

matrices: are character matrices containing IML module statements.
(matrix-names): are character matrices whose elements are the names of character matrices containing IML module statements.

Use the PARSE statement to parse the elements of a character matrix containing IML module statements. For example, the following statement parses the elements (rows) of matrix A as lines of code:

   parse a;

You can parse several matrices with one PARSE statement either by listing all of their names in the statement or by first creating a character matrix, say N, containing their names as elements and then parsing N. Each element of N is the name of a matrix containing IML module statements. In this case, enclose N in parentheses in the PARSE statement to indicate the indirect references to the elements of N.

For example, the statements

   a={"start mod1;",
      "x={1 2 3};",
      "print x;",
      "finish;"};
   parse a;
   run mod1;

produce the result

   NOTE: Module MOD1 defined.

                                X
                                1         2         3

Alternatively, you can use the following statements to obtain the same result:

   a={"start mod1;",
      "x={1 2 3};",
      "print x;",
      "finish;"};
   c={a};
   parse (c);
   run mod1;
