Array question

Hi,
     Another programmer here is having an array problem, and I don't know
how it is happening, or how to fix it. It is a RPG program with a compile
time array.  It is only used in one lookup command.  It is defined
correctly, and works most of the time. We added an output file to the
program so we could see what certain fields contained as the program is
running.  Its a long story, but we are trying to capture the input file
(that causes the error) so we can use debug.  Below is part of the file. At
one point, the array is cleared, and then is repopulated when the next
parent starts. I didn't think a compile time array could work this way!
Anyone have any ideas on why this is happening?

This is the array:
     D ALP             S              1    DIM(26) CTDATA PERRCD(26)
     C     BUB           LOOKUP    ALP(X)
92
     ** ALP
     ABCDEFGHIJKLMNOPQRSTUVWXYZ
