To use the PSX routines, you first need to `log on' for development by using the psx_dev command to create the necessary soft links in your directory so that you can use the short form of the include file names.
% psx_dev
If a FORTRAN program wishes to check for a particular error status returned by a PSX routine, then it should contain the line
INCLUDE 'PSX_ERR'
The use of upper-case in the file name is important. This will define the
symbolic constants listed in appendix .
To compile and link a program that uses the PSX library, type
% f77 program.f -L/star/lib `psx_link` -o program
