maybe someone has an idea

i sometimes work with long strings (i.e. to build an sql or filter command) i then check that string if it is empty with "IsBlank(StrToCheck)".

i gues there is a limitation in IsBlank() since it sometimes triggers the error "string to long to fit".

is there a solution to this problem (i work with vfp6 sp5)?

thanks for all your help in advance.
