Handling Byte Strings (HDS Locators)
Sometimes FORTRAN CHARACTER variables are used to contain strings of
bytes rather than normal, printable character strings - a particular case
of this is
HDS locators.
In this case, special characters, such as NULL, cease to have their normal
meaning and this could confuse the standard CNF import and export functions.
For this reason, functions
cnfImpch
and
cnfExpch
are provided.
These functions just import and export a given number of characters.
