Page fault when adding code

Hello - I'm an ex-mainframe programmer having learned VB on my own. I have a program which works fine and I would like to change the literals on the screens so that the user can choose a language (English, Spanish, etc.) to use. The program works fine, but when I call a subroutine to process nothing but assigns ( A = B, etc.), the program aborts with an invalid page fault. If I do not call the subroutine, the programs works.
It appears to me that I am exceeding a table of sorts, or maybe the limit of some type of memory restrain. I have VB 6 studio, with sp5 and sp6 installed. I'm using indexed and sequential files.

Any suggestions would be much appreciated. Thanks.

Maybe a post of your sub routine would help because then the experts could possibly see where the sub routine is going wrong ?

Ther are several reasons why this can happen. In general it means that you have referred to a memory block (store or call) but the block does not exist. So, pls post the sub code here, and we'll see what we can do.

Hello -
   I did some research on form loading and it appears that the problem is with too many forms loading. When a caption (or other field) is changed on a form, the form is loaded first and the Form_load subroutine is executed within the form. I have abut 20 forms in the program and that creates a problem. In an effort to get it to work, I tried to load the form, make the assignments, then unload the form - but that action did not retain the assignments. So my solution, though a bit tedious, was to replace any Form.Show statements with a call to a subroutine for that form to make the assignments with the proper language and perform the .show within the subroutine. It works.
One other comment: I found a number of notes from others about quirks concerning Windows 98SE, which I am using. Maybe this would not have happened using XP, but I wanted to make the program versital enough for any Windows version.
Thank you for your notes.

So you have 20 additional forms that open when you run the first form ie the main window ? ok now I am lost and do not understand why anyone would want that many forms open at once lol
