Description
Controls the cancellation of a request on truncation of string data. Currently there is just one setting, 1, which means "cancel a request if truncation of string data occurs."
For example, with the default of 0 in place, the following code
%x is string len 1 %y is string len 2 %y = 'ab' %x = %y printtext {~} = {%x}
would cause silent truncation, and give the result
%x = a
If EVALOPT is set to 1, then the above code produces the following message:
M204.0552: Variable too small for result
and the request is cancelled.
