- Pipedream 4 is supplied with an example custom function to Read and
- Write data to a "linking" file. This original custom function is
- incomplete and has a couple of problems! (non-integer parameters
- accepted - causing problem when calculating where to save data. Also
- data block management/size is incorrect.)
-
- Read_Writ6 is my "improved" version (v 1.06) of the above custom
- function. It validates parameters supplied for read and write. It
- also includes a function to reset the whole data block to a set value.
-
- Read_Writ6 caters for 10 "linking file" references (0 to 9) each with a
- block of 80 data items. It should be easy to adapt this to work for
- files transferred from Viewsheet, View Professional, and Pipedream 3.
- It can easily be ammended to increase or reduce the number of data
- blocks ("linking files").
-
- Read_Write is a simplified version (v 2.00) of Read-Writ6 which does
- not use the "file number" parameter (this has not been removed - syntax
- remains compatible with previous versions) and has a single data block
- of up to 800 items. I would suggest using this version for any new
- files which do not require multiple "file" references.

- EXAMPLES
-
- To see how Read and Write work, load the examples from disc in the
- order indicated by their filenames.
-
- (Read_Writ6 is loaded automatically)
-
- Take note of the warning in !Then_me6, and ensure full recalculation of
- this sheet if anything is written to the "link" file after loading this
- sheet!
