Function
In programs written with program templates or when using the
programming support functions, certain machine-specific code lines
may be protected against changes.
A read-only identifier (";*RO*") is tagged onto the code blocks as a
comment. The ASCII editor recognizes these blocks, hides them or
displays them in the read-only text color (gray), and inhibits changes
to these blocks.
Irrespective of the above setting, the user can identify protected
program sections by the "Read Only" identifier (";*RO*").
Any attempt to change a program part protected by the read-only
identifier is denied with the message "Block cannot be written".
Other information
When creating a program template, remember to position the "Read
Only" identifier directly at the end of the block.
