Help with MAT13 error

[Ozmando]

I am geting the following error:

## MAT13. Store into Out-of-Range Matrix or Series Element
The Error Occurred At Location 283, Line 8 of loop/block

The last error shows that the problem is in the last line below at "end".
Any help to solve the problem please?

I'm not sure what:

comp j = 16

is supposed to be doing, since it's followed by the DO J.

The error is in line 8 of the DO J loop, which is

compute lower(j)(i)=frac(1)

I'm guessing that the problem comes from having that SMPL 1 NDRAWS instruction. (Is NDRAWS a small number, at least relative to NSTEP?) That applies to the CLEAR instruction, which you don't want. If you put CLEAR(LENGTH=NSTEP) LOWER(J) ... it will initialize those over the range that they need.

Thanks Tom.
I managed to fix the problem now by running the code portion by portion and all seems to work. I am assuming the error could be because 'end' was written between /* *\, as this is the only thing I have not selected.
Will follow your recommendation though to see if that helps in running the code in one go.
