If you position the cursor in a row marked in red, brief information is displayed telling you the cause
of the error. Notes on correcting the error can be obtained by pressing F1.
Note
If you prefer to edit the variable table with the keyboard (without the mouse), you should keep the
"Brief Information When Using the Keyboard" feature enabled.
If necessary, you can change the setting in the variable table by selecting the menu command Option
> Customize and then selecting the "General" tab.
Maximum Size
A maximum of 255 characters per line are permitted in a variable table. A carriage return into the
next row is not possible. A variable table can have up to a maximum of 1024 rows. This is then its
maximum size.
