Save bug (*solved*)

[Darkstar]

I have not tried to SAVE with 11 chars.

The original BASIC does not accept the command but comes up with: F Invalid file name, 0:1.

The compiled BASIC accepts the command but truncates the last letter when saved to tape but
I do hope that this does not lead to a buffer overflow of sorts.

When saving with an empty string the original gives error message F while the compiled basic just
falls through to the next executable statment giving no clue at all.

Code:

    ERROR_Ok                EQU    -1
    ERROR_SubscriptWrong    EQU     2
    ERROR_OutOfMemory       EQU     3
    ERROR_OutOfScreen       EQU     4
    ERROR_NumberTooBig      EQU     5
    ERROR_InvalidArg        EQU     9
    ERROR_IntOutOfRange     EQU    10
    ERROR_InvalidColour     EQU    19
    ERROR_BreakIntoProgram  EQU    20
    ERROR_TapeLoadingErr    EQU    26

This could be mapped to error #9 but that would not be compatible with the original, I think file operations are important enough to add
error message F.

Otherwise this works fine.
