ERROR: Array subscript out of range at line 1602 column 8.

[Vivian_Vivian]

Hello everyone,

I'm try to use array to transpose long to wide format. However, the log shows "ERRO: Array subscript out of range at line 1602 column 8." Could you please tell me where the problem is?

Thank you so much!

Hello @Vivian_Vivian   Did you notice in your log-  EXAMN=10  while you have only 8 elements in your array? I guess that says it

ERROR: Array subscript out of range at line 1602 column 8.

Thanks for your reply @novinosrin . I only have 8 exams in total (Exam1-EXAM6 EXAM8 EXAM10). The EXAM7 and EXAM9 are missing for every ID in the data set.

[novinosrin]

so of course you can't use the variable EXAMN as array index

[Vivian_Vivian]

Do you mean the array index EXAMN has to be continuous integral numbers without skips?

[novinosrin · Accepted solution]

When you define an array with N elements , the array reference cannot be outside that range i.e For example, should N be 10, the lower bound is always 1 and upper bound is 10. If you happen to reference the array with number say 12  or 0, that implies out of range 

Also please do not confuse with number suffix as an indicator of number of elements in an array

Got it!     thanks a lot ! @novinosrin

Why not just define the array using EXAM1-EXAM10 anyway?

Then the index into the array will match the suffix on the variable name.

You can always drop the EXAM7 and EXAM9 variables if you don't need them.

Yes! That's what I did and it worked out!  Thanks for your reply
