Reserved and user-defined variable names

All variable names in the Pharmacometrics Modeling Language can be user-defined. However, some variable names are reserved for syntactical reasons.

When building a model, the following should not be used as variable names:

Words that are already part of the Pharmacometrics Modeling Language

Words that are reserved for NLME (case sensitive): cabs, hypot, chgsign, copysign, logb, nextafter, scalb, finite, pfclass, repl, isnan, j0, j1, jn, y0, y1, yn, UNI

Words that are in the C runtime or C math libraries

Words that are GNU library calls or GNU reserved words (for a list of GNU reserved words, see gcc.gnu.org/onlinedocs/gcc-8.4.0/gcc/Keyword-Index.html)

If a reserved word is used, it will cause a compilation error when the model is being built and will appear in the model code as blue text.

Some common reserved words to avoid:

    bioavail      event         rate
    bolus         first         real

    break         for           return
    call          gamma*        same
