8  Introduction

This document describes features of the NONMEM system that are not described in the Users Basic Guide, i.e. NONMEM Users Guide, Part I. Note moreover, that some features described here are not available with Version I, or with just Version I Level 1. Such circumstances wherein features are not available, are given in the text.

The computer output shown in the figures from the examples of section D is obtained from the Control Data Corporation version of NONMEM, rather than from the IBM version. The CDC version is not being distributed. The computer output shown in the figures from the example of section C is obtained from the IBM version of NONMEM, Version II Level 1.

We take this opportunity to mention some miscellaneous points that were not made clear in the Users Basic Guide.

• The same ID data item may be used to identify two different individual records, providing these records are not contiguous in the data set.

• When the MDV data item of a data record is 1, the DV data item of that record is not included in a SCATTERPLOT in which DV data items are plotted on either the ordinate or abscissa axis.

• The width of an A format code appearing in a FORMAT record should not exceed 4 (the no. of bytes in an IBM word). A data item read with such a code should not be tabled.
