A block groups several constructs in a single unit. Blocks have to flavours: [...$] or /name/...$/name/. The later is called named block and wsh pairs the starting and ending name (improved source readability). Furthermore, wsh can use the block name, e.g. an assignment or proc definition may be abbreviated.
A block is interpreted as a sequence of statements that may be run (object of class ORun), but is often casted by implicit or explicit operators. e.g. the primary $-[time()$] produces the result of the rexx time() function as a string.
a block can only be preceeded by operators, if it is preceeded by a kind, because wsh assumes default kind and operators, sometimes several copies of the same operator character are needed
