-====== PPL source syntax ======
-Each line of a PPL source file may contain none, one, some or all of the following sections:
-^[KEYWORD ][EXPRVAR][,EXPRVAR][;'][COMMENT TEXT]^^^^|
-|KEYWORD|A PPL statement used to accomplish some task.  | | | |
-|EXPR|A PPL expression which may contain VARs, CONSTs, and/or FUNCs.| | | |
-|VAR|A PPL variable with optional array subscript.| | | |
-|CONST|A PPL constant.| | | |
-|FUNC|A PPL function that returns a value.  | | | |
-|;|Used to start a comment. Ignored by the compiler.| | | |
-|'|Used to start a comment. Ignored by the compiler.| | | |
-|*|Used to start a comment if first character of the line.| | | |
-|COMMENT|Comment text following the ; or '. Ignored by the compiler| | | |
-If a line is blank or contains only a comment, it is skipped. if it contains a KEYWORD, that line is compiled into a tokenized format. If it doesn't contain a KEYWORD but some argument, it is assumed to be an assignement statement (LET).
-A double quote ("") may be embedded within a string constant to tell the compiler that a single literal quote is desired In other words, "THIS""IS""A""TEST" would evaluate to THIS"IS"A"TEST after the leading and trailing quotes are removed and the double quotes were folded to single quotes.
-Labels and variable names may now include the following characters in addition to A-Z, 0-9, and the _ (underscore) character: $ (dollar sign), @ (commercial at), # (pound sign), ¢ (cents), £ (british pound), ¥  (japanese yen)
-A \ (backslash) character as the last character on a line (before any comments) will now allow continuing a logical line from one to the next physical line
-A : (colon) character may be used to separate multiple logical lines on a single physical line
