Thanks for the Info.

For my problem with HEX calculations I have found a solution
Involving breaking the number into 2 sets of three Hex digits and using 
FLOAT and FIX to convert to REAL for the Math and then back to Integer 
to PRINT USING H3.

I an ready to go on to the next step where I want to pass
parameters from the command line to my program, so not having written 
basic09 code in 15 years I looked for a sample program from  the manual.

The program I found I have listed below.

PROCEDURE add
PARAMETER a,b
PRINT a+b
END

This is exactly as I wrote it as I used list add>/p
to send it to a file on my PC and then cut and pasted it into
this email.

But something is wrong as I get these errors.

add
PARAMETER a,b
           ^
ERROR #027
ERROR #051
Ready
B:


Help Please!
