The PPINCLUDE option specifies options to be passed to the INCLUDE preprocessor if it is invoked.
.-NOPPINCLUDE-----------------------. >>-+-PPINCLUDE--(--'options string'--)-+-----------------------><
Specifying PPINCLUDE('ID(-inc)') PP(INCLUDE) is the same as specifying PP(INCLUDE('ID(-inc)')).
This option has no effect unless the PP(INCLUDE) option is specified. However, if you want to specify a set of INCLUDE preprocessor options that should be used if and when the INCLUDE preprocessor is invoked, you can specify this option in the installation options exit. Then whenever you specify PP(INCLUDE), the set of options specified in the PPINCLUDE option will be used.
Also, any options specified when the preprocessor is invoked overrule those specified in the PPINCLUDE option. So specifying PPINCLUDE('ID(-inc)') PP(INCLUDE('ID(+include)')) is the same as specifying PP(INCLUDE('ID(-inc) ID(+include)')) or the even simpler PP(INCLUDE('ID(+include)')).
The options string is limited to 1000 characters in length. However, if the string is longer than 100 characters, it will not be shown in the options listing.
