MATREAD Syntax MATREAD dim.array [FROM [file.var,]record.ID.expr [ON ERROR statements] {THEN statements [END] | ELSE statements [END]} Description The UniBasic MATREAD command assigns the values found in successive attributes of a record to corresponding elements of a dimensioned array — regardless of lock status. You must use the DIM command to create a dimensioned array before you execute MATREAD. Note: This command does not check for locks. If you are operating in a multiuser environment, you must use record locks to prevent users from overlaying data updated by others. For more information about the UniBasic record locking, see Developing UniBasic Applications. Parameters The following table describes each parameter of the syntax. Parameter Description dim.array Specifies the dimensioned array into which the values are read. FROM file.var, Specifies the file from which to read. If you do not specify a file.var, UniData reads from the default file. If no default file is open, a fatal READ error occurs. A default file is one for which no file variable is assigned in the OPEN statement. record.ID.expr Specifies the record from which to read. MATREAD Parameters MATREAD 1-449
