List.tr(dataIn,dataOut)

This operator allows simple single character string manipulation. It computes a new list, copying each character of the source list but converting any characters in dataIn to the corresponding characters in dataOut. For example:

$MyList.tr("a","A") 

returns a copy of $MyList in which every "a" is converted to "A".

Backslash characters must be quoted and escaped:

$MyList("c","\\r") 

converts every "c" to a Macintosh newline characters (\r) - note the need in this context for an extra backslash escape (so Tinderbox knows the intended swap value is "\r" and not "r").

For further information, see the Mac OS X man page for the UNIX tr command.
