Option Base

[Joe Caverly]

If it would not be a nightmare to modify the TCC source code,
I would like to suggest adding the ability to define the default lower bound for arrays and commands/functions,
to either 0 or 1,
for example,
in the @LINES function;

The first line in the file is numbered 0,
so (for example) @LINES will return 0 for a file containing one line.

To get the actual number of lines,
use %@INC[%@LINES[filename]].

For arrays;

You can define up to 4-dimensional arrays. For example, to define a 5-row by 10-column array:

setarray array1[5,10]

The array elements are addressed in base 0,
so to reference this array you would use 0-4 for the rows and 0-9 for the columns.

...and all of the other TCC functions and such that have the base 0.

The FileUtils plugin has the LINES command,
which returns;

R:\>lines zoom150.btm
File “R:\zoom150.btm” :
   Total lines:          49   Blank  :           4   Not blank:          45
   Comments   :           9


R:\>echo %@lines[zoom150.btm]
48

In this case,
I prefer 49 to be the number that I use for the lines in the file,
not 48.

While most modern programming languages default to zero-based indexing,
having the ability to change the Option Base would allow TCC users to shift this starting point.

Maybe create a new command called OptionBase,
that would accept either 0 or 1 to determine whether elements begin at either 0 or 1.
