This program is designed to run BASIC code from ECL/TCL.

** Program Type-: Utility
!
** Notes:
**
** This process simply builds a BASIC program from the command line,
** compiles it, runs it, decatalogs it, then deletes it.  Multiple
** lines can be created at 'TCL' by separating them with a ';'.
**
** This program will parse out each line and create it as a separate
** line in the temporary program.  Of course, a ';' can be part of
** a quoted string but cannot be part of a comment.
**
** It's always a good idea to use 'END' statements, e.g.
**
** :BPTEST PROMPT '' ; C.BCK = @(-9) ; TEST = "NOW IS THE TIME" ; ANS = '' ;
**  LOOP UNTIL ANS = 'X' DO ; ECHO OFF ; INPUT ANS,1 : ; ECHO ON ; IF ANS 
**  NE "<" THEN CRT ANS : ELSE CRT C.BCK : ; REPEAT ; END
