Interface File entries specifying help libraries may be given as standard pathnames e.g.:
Note that the file extension .shl is optional.helplib /star/help/kappa/kappa.shlorhelp %/star/help/kappa/kappa ADD Parameters IN1
The system will also accept environment variables and ~ in the help library name, e.g.:
$KAPPA_DIR/kappahelp.shl or $KAPPA_HELP or ~/help/myprog
For historical reasons, so that the same Interface File entry will work with both Unix and VMS, the VMS form:
KAPPA_DIR:kappahelp.shl or KAPPA_HELP:will be accepted.
If the VMS form is used, the environment variable name will be forced to upper case, and the filename to lower case for interpretation. Unix-style specifications will be interpreted as given.
