BRIDGE DOCUMENTATION
This bridge can import the .pos format file.

MIMB allows you to define the structure of a positional file by specifying it manually.
You do not need to change the name and path of the file.
You just need to define the list of columns it has and their positions using comma-separated values.

The list of rules of the internal structure of a file:
- Format file must start with the following header:
column name, position, width, data type, comment
- All positions must be unique and greater than or equal to 1.
a,1
b,5
- The file format is invalid when some columns have positions and others don't.
a,1
b,
c,5
- When all columns do not have positions but have widths the application assumes that columns are ordered and calculates positions based on widths.
a,,4 -> a,1,4
b,,25 -> b,5,25
- When the position is present the application uses widths for documentation only.
a,1,4
b,5,25
- Types and comments are used as documentation only.
a,1,4,int
b,5,25,char[25],identifier
