B-3
LS String Too Long: A string variable was assigned a string value which exceeded 255
characters in length.
ST String Formula Too Complex: A string operation was too complex to handle. Break up the
operation into shorter steps.
CN Can't Continue: A CONT was issued at a point where no continuable program exists, e.g.,
after program was ENDed or EDITed.,
NR No RESUME: End of program reached in error-trapping mode.
RW RESUME without ERROR: A RESUME was encountered before ON ERROR GOTO was
executed.
UE Unprintable Error: An attempt was made to generate an error using an ERROR statement
with an invalid code.
MO Missing Operand: An operation was attempted without providing one of the required
operands.
FD Bad File Data: Data input from an external source (i.e., tape) was not correct or was in
improper sequence, etc.
L3 DISK BASIC only: An attempt was made to use a statement, function or command which is
available only when the TRS-80 Mini Disk is connected via the Expansion Interface.
Hard-To-Find Errors
Shifted-characters aren't always interchangeable with their unshifted
counterparts. For example, PRINT @ won't work with a shifted-@ even
though it looks OK on the Video.
If you can't find anything wrong with a line that causes a syntax error, try
retyping it and watch out for the SHIFT key.
Spaces are sometimes important in LEVEL II BASIC. For example,
IF D<0D=0
will not work because 0D in the middle is interpreted as double precision
zero. Change it to
IF D<0 THEN D=0
