C-ISAM, adding fields
Posted 26 October 1999 - 02:48 PM
I'm using SCO 5.0.5, pro4 ver 4.5.32
I've got to add some fields to a C-ISAM file. [THe file has Alternate Indexes].
In the past I've
1-made a new file def. using @CFIL.
2-insert the new fields.
3-rename the indexes for new def.
4-create the new c-isam file
5-then copy the data from the old file to the new.
Is that the only way to add fields to a c-isam file?

fields, ie a few numeric spares and some alpha spares.
Then you can still add some new numerics, and chop up
the alpha spare into pieces.
You do have to watch the record size to make sure you don't
change it, and it does use up space in the file.
(It would be nice if varialble length c-isam was available for
us, but Pro-IV never replies to my requests about how

Create variable length file(s) if filetype is C-ISAM.
I've been able to create variable len c-isam files. But I've not been able to figure out how to do so and have alternate indexes.
Some of the other 'is' utilities have variable legnth c-isam flags..
I've ask pro4 tech support about their use but have not gotten an answer despite asking many times and ways.
