In order for the &lnkname to locate the &prod16 and &prod32 library
files, the
.ev &pathvarup
environment variable should be defined.
.if '&target' eq 'QNX' .do begin
When using
.kw &wclcmdup
.ct , it is not necessary to define this environment variable since it
uses another technique for identifying the location of the library
files to the &lnkname..
However, you should do so when you begin to use the &lnkname directly
without the aid of this utility program.
.do end
The
.ev &pathvarup
environment variable is used to locate the libraries that will be used
when the application is linked.
The default directory for &prod16 and &prod32 files is "&pathnamup".
