# an example program to test the std_lex module --ksb
# Build a lex parser with this 5 line spec:
#	%%
#	[0-9]	{ return yytext[0] - '0'; }
#	[a-f]	{ return yytext[0] - 'a'+10; }
#	[A-F]	{ return yytext[0] - 'A'+10; }
#	\n	{ 0; }
#	.	{ return  -1; }
# mkcmd this file, compile prog.c
# the program should convert Hex digits to Decimal -- kinda.
# note is acts like a filter mostly.
