getdate

DOCUMENT date = getdate();
      or getdate, date;

SEE ALSO: gettime, parsedate, timestamp.

gettime

DOCUMENT time = gettime();
      or gettime, time;

scalar

DOCUMENT scalar -- get optional scalar parameter

PROTOTYPE
  x = scalar(xarg, xdef, lt=, le=, gt=, ge=, type=, arg=, fn=);

ARGUMENTS
  XARG    argument passed to the function.
  XDEF    default value for the scalar argument (optional, if not
          specified, then it is guessed that the caller must supply the
          argument).
KEYWORDS
  GE=     to be valid, XARG must be >= GE (optional, only one of GT or GE
          can be used).
  GT=     to be valid, XARG must be >  GT (optional, only one of GT or GE
          can be used).
  LE=     to be valid, XARG must be <= LE (optional, only one of LT or LE
          can be used).
  LT=     to be valid, XARG must be <  LT (optional, only one of LT or LE
          can be used).
  TYPE=   data type of the scalar (optional).
  FN=     function name for error messages (optional string).
  ARG=    argument name for error messages (optional string).

DESCRIPTION
  Check XARG and return a scalar value (i.e., either XARG converted to TYPE
  if it is not void or XDEF otherwise).  If XARG is not within any specified
  bound or if it is not a scalar or if it is void (e.g., not specified) and
  there is no default value XDEF, an error message is written out.

EXAMPLE
  The following function has 2 scalar arguments X and Y, the 1st one is an
  integer (of type long) which must be specified and be strictly greater
  than 22 while the 2nd default to .5 and must be in [0., 1.]:
    func foo(x,y) {
        x= scalar(x,     gt=22,        type=long,   fn="foo", arg="X");
        y= scalar(y, .5, ge=0., le=1., type=double, fn="foo", arg="Y");
        ...
    }

WARNING
  There is no checking of consistency of options.
