* Function name: printremark ( string )
* Synopsis: Print the given string as a series of "Remark" lines,
* (i.e., preceded by backslash-space)
*
* Inputs:
* Parameters:
* str Pointer to the start of the string,
* however long it may be. The string
* may have any number of embedded new-lines.
*
* Outputs:
* Returned Value: *** NONE***
* Printout: Each line of the string will be preceded by
* a backslash and two spaces. Backslash-space
* is the standard delimiter for a "remark", i.e.
* the entire line is ignored as a comment. The
* second space is "just" for aesthetics.
*
* Process Explanation:
* Parse the input string for new-lines. Print each separately.
* Do not alter the input string.
*
*
* Still to be done:
* Define a routine, call it PrintComment , to print the given
* string surrounded by open-paren-space ... space-close-paren
* Define a single central routine, call it safe_malloc ,
* to do the test for null and print "No Memory" and exit.
* Define a single central routine, call it PrintError , to:
* Print the given error message
* Show the input file and line number
* Collect error-flags for failure-exit at end of operation.
*
