Write a character string

Syntax: | `WRITE\TEXT file txtvar`
Qualifiers: | `\APPEND`
Examples: | `WRITE\TEXT FILE.DAT T WRITE\TEXT\APPEND FILE.DAT T`

The `WRITE\TEXT` command writes writes a character string to a file. If `\APPEND` is used, and if the output file already exists, the string will be appended onto the end of the file.

Example 1

The values of scalar variables can be written by using the `RCHAR` function and the append operator, `//`. For example:

     WRITE\TEXT FILE.EXT `The value of A is '//RCHAR(A)
     WRITE\TEXT FILE.EXT `The value of X['//RCHAR(J)//`] = '//RCHAR(X[J])

Example 2

Suppose you want to write a header line to a file and then write some data stored in vectors to that file. For example:

     WRITE\TEXT FILE.DAT `This is a header line'
     WRITE\APPEND FILE.DAT X Y Z

Suppose `X` is a vector, `X = [ 1.1; 2.2; 3.3; 4.4 ],` and you want to write the values of `X` to a file, with some text. For example:

     DO J = 1, LEN(X)
      WRITE\TEXT\APPEND FILE.DAT `X['//RCHAR(J)//`] = '//RCHAR(X[J])
     ENDDO
