| ### Last Operation's Return Value (_r) The _r variable holds the return value of the most recent operation. Many dcecp commands return multiple lines of output which are in the form of a list. The following example shows one use of the _r convenience variable. The dts show command returns multiple lines as a list. The attrlist getvalues operation (see the attrlist(8dce) reference page) searches through the returned list for the string toofewservers and returns its associated value. dcecp> dts show -counters {creationtime 1994-09-16-07:50:13.067-04:00I-----} {nointersections 0} {nointersections 0} {diffepochs 0} {toofewservers 1} {providertimeouts 82} {badprotocols 0} {badtimerep 0} {noglobals 81} {noresponses 0} {abrupts 0} {epochchanges 0} {syserrors 0} {syncs 1574} {updates 0} {enables 1} {disables 0} {nomemories 0} {providerfailures 0} {badlocalservers 0} {badservers 0} dcecp> attrlist getvalues $_r -type toofewservers 1 dcecp> ###
