BASIC ERROR MESSAGES
In most cases, when an error occurs in a BASIC
program, the Interpreter returns to the command level.
This is designated by the "]" prompt and a flashing
cursor. The program remains in memor y, and the
variables are set at the values they had assumed at the
time the error was encountered.
You can use the PRINT command in direct mode to
ascertain the values your program variables had at the
time of the error.
To avoid your program stopping on coming across an
error, you can use . error trapping. See the ONERR
GOTO statement for an explanation of how to use this
technique.
