Description
The user parameter EVALOPT allows optional modifications to evaluation behaviors. The bits in EVALOPT have the following meanings:
| X'01' | If on, the evaluating request will be cancelled on truncation of a data string. |
|---|---|
| X'02' | If on, the evaluating request will be cancelled on a non-convertable number. |
| X'04' | If on, nulls will be considered as non-convertable numbers. |
For example, consider the following code:
%v is string len 2 initial('ST') %s is string len 1 %f is float %n is float %s = %v %f = %v %n = printtext {~} = {%s} printtext {~} = {%f} printtext {~} = {%n}
If EVALOPT is set to 0 (default), then the above code would allow silent truncation and give the result:
%s = S %f = 0 %n = 0
If EVALOPT is set to 1 , then the above code is cancelled with the following message:
M204.0552: Variable too small for result
If EVALOPT is set to 2 or 4 , then the above code is cancelled with the following message:
M204.2985: Invalid numeric conversion
