Note that in a procedure you should not use any of the parameters to that
procedure as your SELect variable.
Instead of :
DEFine PROCedure menu (a,b,c)
SELect ON a
..... ......
..... ......

You should use :
DEFine PROCedure menu (a,b,c)
LET choice = a
SELect ON choice
..... ......
..... ......
..... ......
The SELect variable must not be a string variable or an integer/
Has anyone ever come across this - or indeed, has anyone ever come across this
as an issue?
Yes. The variable for a SELect clause must be floating point. In SuperBASIC you
can, oddly, have parameters a, b and c any type- integer, floating point or
string. Hence the need to force the parameter to floating point by LET choice =
a.
I actually have several programs where I have had to make this adjustment.
Minerva did not have this "feature" and one could select with any
variable type.
