Good day, I have a concern regarding errset command when used in calculator (CALC) commands; I want to contain CALC errors into a list. In the example below, when I invoke errset("clip(v("net31" ?result "timeSweeptran") 1u 2u)") to "catch" the error using errset, the result is errrset("clip(v("net31" ?result "timeSweeptran") 1u 2u)") SYNTAX ERROR found at line 29 column 23 of file *civInPort* *Error* linread/read: syntax error encountered in input I follow it with errset.errset to see the list that contains the error but the result is (nil). Here, I only want to get errors of CALC functions (cross, average, clip, abs). How do I solve this problem? Your suggestions and comments would be of great help. Thank you very much.
