Characters not displaying in a field?

[kee nethery]

I'm trying to put 140000 characters into a field, no spaces. The put 
into field statement has two variables that get concatenated

put return & variableA & return & bunchOCharacters into field "thefield"

VariableA shows up in the field but bunchOCharacters does not

When I copy the contents of the field and paste into a text document, 
the bunchOCharacters data is in the text document

What's up? Why does the text, bunchOCharacters, not display in the 
field?
