What follows is the comment header of EVAL.rexx

/****
*   Enhanced "c:Eval" Command
*
*   With trig and other functions
*   see REXXMATHLIB.library for fuction details
*
*   syntax is the same as the rexxmathlib function calls
*              ie: func(x[,y])
*          OR spaces may be used as deliminators (in all funtions)
*              ie: func x [y]
*
*   There are two extra functions:
*
*   1)   DEG(deg,min,sec) outputs Decimal degrees
*     or the alternative syntax is DEG(dd.mmss)
*
*   2)   DMS(DD.dddd) outputs dd mm ss
*
*
*   If the function is unknown to rexxmathlib then the original line is
*      passed, as typed, to the c:eval function. This alows for all the
*      original "eval" maths (and syntax) to be used as a failsafe.
*
*
*   Add the line
*         Alias  Eval  rx rexx:eval.rexx []
*                 into the s:shell-startup script and use in any Shell
*                 syntax:  eval func(x[,y])  OR as per dos EVAL command
*   Put eval.rexx into rexx:
*   and rexxmathlib.library into libs:
*
*     NOTE: all angles are input as decimal DEGREES    (NOT radians)
