9DCD '<' operator

Submitted by Steve Fewell

Description:

Check the next character from the BASIC Input line. If the next character is '=' then
the operator is '<=' Less Than or Equal To, so jump to &9DE1 to handle this operator.
If the next character is '>' then the operator is '<>' Not Equal To, so jump to &9DEC
to handle this operator.
Otherwise the operator is '<' Less Than. which is handled as follows:

Call &9CC9 to Compare the current value with the second value and set the flags
according to which value is greater, or whether the values are equal.

If the carry flag is clear then the first value is less than the second, so set the
IWA to TRUE; otherwise, the first value is not less than the second, so set the IWA to FALSE.
Exit with A = #&40 (as we are currently handling an Integer value).
