FileGetCol function HELP states that if a column value including terminating null character is larger nMaxLen parameter value, the return value is truncated accordingly.   What actually happens is that execution terminates with the error RESERR: 180 - Buffer passed to function is too small to hold data.

The severity of the RESERR: 180 - Buffer passed to function is too small to hold data message should be Warning.  This will be fixed in a future version. 

In the meantime it is possible to manually modify the severity of the error to warning using the instructions:

  • SETTINGS | ACTIVE PROFILE | SIMULATION | ERRORS tab | ADD
  • Select "SilkPerformer - RESERR" from the Module drop down
  • Enter "180" into the Error code field
  • Select Succes/Warning from the Custom severity down
