`print, var1, var2, ...` | print the values of the varI
`info, var` | print a description of var
`dimsof(x)` | returns [#dimensions, length1, length2, ...]
`orgsof(x)` | returns [#dimensions, origin1, origin2, ...]
`numberof(x)` | returns number of elements (product of `dimsof`)
`typeof(x)` | returns name of data type of x
`structof(x)` | returns data type of x
`is_array(x )` | returns 1 if x is an array, else 0
`is_func(x)` | returns 1 or 2 if x is an function, else 0
`is_void(x )` | returns 1 if x is nil, else 0
`is_range(x)` | returns 1 if x is an index range, else 0
`is_stream(x)` | returns 1 if x is a binary file, else 0
`am_subroutine()` | 1 if current function invoked as subroutine
The `print` function returns a string array of one string per line if it is invoked as a function. Using `print` on files, bookmarks, and other objects usually produces some sort of useful description. Also, `print` is the default function, so that expr is equivalent to `print,` expr (if expr is not a function).
