Maximun length of variable?

[Del]

Hi:

I am working on a program I did not write.  There are lots of errors that I have been asked to correct.
At one point in an output process, a variable “Z” is used with no length or edit type.
It is basically used as a bucket to build a string of text characters and print output control characters prior to generating an output string in an EXPORT process.
Because of the way this is built, using repetitive looping, it has the potential to get very long.  
Does anybody know if there is a length limitation in filePro for such a text string?
I am concerned that at some point it could exceed a length limitation, and I seem to recall reading something about that at some point, but I can no longer remember where.
