exchange() function

The exchange() function replaces the characters specified in str.exp1 with the characters specified in str.exp2.

Syntax

exchange(var, str.exp1, str.exp2)

`var`	Variable in which the specified string will be searched and replaced.
`str.exp1`	Specifies the characters to be replaced with the corresponding replacement characters from `str.exp2`.
`str.exp2`	Specifies the characters to replace the characters specified in `str.exp1`.

This function works identically to the convert() function except that the second two arguments are specified as hexadecimal numbers.

Note: This function requires a nondefault compiler setting. Inserting the line $options ext at the beginning of the source code accomplishes this.

The result, bbc, displays on the terminal.

crt exchange("abc",dtx(seq("a")),dtx(seq("b")))
