Text Files Come to Unibase by DMAC Release 7.46i to Make Easy Access

Unibase by DMAC, release 7.46i, now has complete support for handling text files. These text files can be created within Unibase by DMAC or come from anywhere else. The pattern of verbs in the AID language for text support is similar to that for handling data batches or indexes on a channel. The following verbs (shown with an example usage) allow all possible manipulations of these text files:

define text txtnam with dirnam /filnam (record length; key length; key offset; record type).

open txtnam[|upd] [with delete] [else . . .].

[with create]

close txtnam [with delete].

append txtnam from arraynam.

get [first] txtnam [using key] into array else . . . .

[last]

[next]

[prior]

[current]

put txtname from arraynam.

concatenate var1 to var2.

The concatenate verb is used to define text file names on the fly in the edit program. All text files are stored in the text directory in the Unibase by DMAC environment. Currently when used as a keyed file (or indexed file), the text file records must be in ascending order based on the key.

These changes to Unibase by DMAC were made in release 7.46i so that conversion from REI/Banktec Tartan would be easy and straight forward. (See the articles in the Winter, 1998 issue of "The Unibase Technical Review.")

This gives a longer than usual beta/quality assurance time for 7.46i; but we hope users feel it has been worth the wait. The readme file which comes with Unibase by DMAC dated May 10, 1999 or later has a complete description of these verbs. Also the new manuals (first shipping in July, 1999) will have the verbs for text processing in them.
