The op parameter now supports a +2 flag to cause it to recognize quoted arguments. For example, consider the following string:
"DSK0:A.B[111,222]",ARG1,ARG2
If the field delimiter is a comma, normally STRTOK would parse the arguments like this:
"DSK0:A.B[111
222]"
ARG1
ARG2
By adding +2 to the OP parameter, it will parse it like this:
DSK0:A.B[111,222]
ARG1
ARG2
Note that it removes the quotes.
