Block Delimiters
EQUEL block delimiters mark the beginning and end of the embedded block-structured statements. The retrieve loop and the forms statements display, unloadtable, submenu, formdata, and tabledata are examples of block-structured statements. The block delimiters to such statements are the keywords begin and end. For example:
##  retrieve (ename = emp.name)
##  begin
    writeln(ename);
##  end
Other EQUEL languages use braces to delimit the blocks. The EQUEL/Pascal preprocessor treats those delimiters as comment delimiters.
