TURBO_model “ [ < | > ] “


Turbo Toolkit v3.00+

This is a directive for the TURBO compiler and should be located at the start of your program before any active program lines. The TURBO compiler is able to generate code using either 16 bit addressing or 32 bit addressing. The former produces more compact and slightly faster code than the latter, but runs into problems if the compiled version of your program (excluding dataspace) is larger than 64K. You should therefore experiment with this setting - if your program is too large to be compiled with 16 bit addressing, the TURBO compiler will report an error during the code generation stage to the effect that the program is ‘too large for optimisation’. This does not overcome the problem with running TURBO compiled programs on systems which have a lot of memory or which do not have the system variables stored at $28000. To cover these programs, it is necessary to run them through the TurboPatch program supplied with later versions of the TURBO toolkit.

The TURBO_model directive accepts a single character string which should be one of the following values:

  • <: Generate code using 16-bit addressing (shown as <64K on screen).

  • >: Generate code using 32-bit addressing.

As with other compiler directives, this value can be changed by configuring the parser_task program or by entering a different value on the Parser’s front panel.
