Table 4.2 st20cc options for C++

Environment variables
One additional environment variable is supplied (ST20EDGARG) which may contain the
default switches to the C++ preprocessor. For UNIX and Linux use, this should only
contain spaces in the list of values if all the values are enclosed inside double
quotation marks for example, “value list”. Preferably all quotes and spaces
should be removed, for example:
setenv ST20EDGARG “-tused,-i”
set ST20EDGARG=-tused,-i
