Details
The nwsFindTryFile
method looks in the shared netWorkSpace .Object
for a value bound to xName
; if it finds such a value, nwsFind
writes it to the specified file but does not remove it from the variable, and returns TRUE
.
If no value is found, nwsFindFile
returns FALSE
.
If there is more than one value associated with xName
, the
particular value returned depends on xName
's behavior. See
nwsDeclare
for details.
