Hi Sarah,

You can use LEN() function to get the lenght of VFP string.

IF LEN(lcStr) <= 65535 
* The size of the string is less than or equal 64K
ELSE
ENDIF

You can also modify UDF's you're using so they can handle longer strings.

>>Be carefull with strtofile and filetostr UDF's for VFP5 you found because they may be limited to file size of 64K.
>I've been thinking about this and pondering some other code which uses strtofile. In this I work through a table and create html which I output then pop a browser. How do I test that my string doesn't exceed 64K.
