<p>PURPOSE:To easily set a retrieving key at call of the data by using the data which are called and displayed as the retrieving keys for the subsequent calls. CONSTITUTION:A display means 5 is prepared together with a storage means 3 which stores the data used as the retrieving keys at call of the data, and a means 1 which stores at least a part of the data displayed on the means 5 into a storage means 10. That is, the character string stored in an input/output buffer 10a of a data RAM 10 is saved into an area called DSSTR secured in a work RAM 3 when the registered data are read out and displayed or the data are called out. Then the character string stored in the RAM 3 is used as a retrieving key. Thus it is not required to interrupt a data calling process nor to input again the retrieving key. Thence, the retrieving key can be easily set.</p> |
