[fpc-pascal] How to initialize a "Text" variable?

[Sam Liddicott]

Find the definition of the "text" type and see that it contains pointers to read and write functions.

They need replacing in yor instance to pointers to functions that do nothing.

The original Pascal file access is object oriented after all!

I'm not sure if mixing lexlib (which is AFAIK written using procedural TP
style code) with streams is a good idea. Depending on your platform, you
could probably simply assign the text file name of 'NUL' or '/dev/nul'.
Admittedly, I don't know whether this kind of device exists for all
platforms (e.g. Symbian ;-) ).
