StringTable
Inputs
TABLE : STRING Name of the Sting Table resource - must be a
constant
COL : STRING Name of the column in the
table - must be a constant
Outputs
OK : BOOL TRUE if OK
Remarks
This function selects a column of a valid String Table resource to become the active string table. The LoadString() function always refers to the active string table.
Arguments must be constant string expressions and must fit to a declared string table and a valid column name within this table.
If you have only one string table with only one column defined in your project, you do not need to call this function as it will be the default string table anyway.

Ladder logic is a method of drawing electrical logic schematics. It is now a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them
