Thanks for the reply Nick. Apologies for not following protocol. The user-written program was sourced as with the reference you mentioned below.

I have now acquired full administrative access however still cannot run the command.
The error post __000003 not found, r(111), still shows up.

Any new ideas would be appreciated

Sid

-roctg- is a user-written program from SJ. Please remember that you
are asked to explain where user-written programs you refer to come
from.

SJ-2-4  st0025  . . . . . . . . .  Two-graph receiver operating characteristic
        (help roctg if installed) . . . . . . . . . . . . .  M. E. Reichenheim
        Q4/02   SJ 2(4):351--357
        command for visualizing sensitivity and specificity curves
        according to the range of values of a new diagnostic test,
        given a "true" state of an event, the reference test

-roctg- is trying to -post- results to a temporary file and failing.
My guess is that you are working in a directory or folder, perhaps on
a server, in which you have no write permission, i.e. you cannot
create new files.
