int doCalculation

(

char *

buf

)

Bug:

lcalc exits if there is a math error;
must set in place a math_err handler
Also, the command line args are not evaluated first.
lcalc doesn't know what to do with the command and exits.

int doLetCmd

(

char *

buf

)

in the form:

let variable = expression
now can be called with just variable = expression

Bug:

Can not modify a header variable. If called with a header variable,
then system will create a dynamic variable with the same name.
Probably not what you want.
Need to change this behaviour
