Puzzle between lower and upper case

[Fred Katzel]

Hi all,

Recently I was writing a program that uses e and E as variables
only to find at after calculating e and then calculating E the
program placed E to the variable e. I thought that e and E would
be separate variables. Could someone enligthen me.

The BASIC language is not case sensitive.

To expand a little on Jose's response:

"variable$", "Variable$" and "VARIABLE$" are all the same to
a basic compiler.

A good work around, in your case, would be e1$, e2$, etc. just
keeping in mind that caps are immaterial.

$DIM ALL would have forced you to use LOCAL on both E and e and caught that with a '466 duplicate name definition' error

(Actually, just 'LOCAL E AS LONG, e AS LONG' catches this even without $DIM ALL.)
