"String too large" error in xrun command (with Matlab)

[Hvtcapollo]

Dear all,

When I use Eviews COM client connected with Matlab and use command "xrun A" to execute a command A in Matlab I got the error message "string too large", even thought the command A is in fact executed in Matlab already ( I saw the result in matlab). Has anyone experienced this problem? if yes, would you help me out of what this message actually means?

Many thanks,
