Whenever C code is generated for a Process, a Function or an OAM, referenced text strings are defined in a file with the same name as the object, followed by a txt suffix.
Within these .txt files is defined every text string as a Unicode value.
The Unicode form is used because it cannot be corrupted by page code variations when you transfer source code from platform to platform.
The actual conversion of the strings to hexadecimal form involves the use of automatic conversion tables provided by the operating system. This is performed as part of compiling on the target platform and produces a .UTX file which is compiled into the executable object.
