They would, however, allow modifications to be made to the example module which would make it more memory efficient. These are changes to the definition of the type so that by default all strings are created with the pointer component diassociated. The "defining" procedures such as the assignment and input subroutines can then safely test for the association status of the argument which is to become defined in the invocation and free any memory by dallocation if the string is currently allocated. The required changes amount to about 10 lines of changed code in the source of the module. In addition there are a small number of errors in the published document which should be corrected. Again I am aware of only a couple of code errors in the example program VOCAB.F90 that need correcting. Given the small number of changes required it is recommended that the base standard is not republished but an addendum document is produced indicating the necesary editorial changes to the existing published document. The existing unammended document will continue to be the Fortran 90 auxilliary standard and the existing document plus addendum will provide the Fortran 95 version of the auxilliary standard. An updated version of the source code can be found on the web. http://www.liv.ac.uk/~jls/iso_vst.f95 I dont guarantee I have found all the desirable changes, nor that I have made those that have been done correctly. Until I can gain access to an F95 compiler the proposed mods cant be tested. I would welcome comments. - -- Dr.J.L.Schonfelder Director, Computing Services Dept.
