Outputting Isodraft Symbols

When you have defined the symbols you require in the Symbol Library, you must output the Symbols to an Isodraft Symbol File using the ISOSYMBOL command. You can open a new (or existing) file by giving the command:

ISOSYMBOL filename

The current symbol (that means, ISOTM) can be added to the file by:

ISOSYMBOL ADD

A symbol that has been added but is not required can be removed from the file by giving the command:

ISOSYMBOL DELETE skey

When all the symbols have been added, the file is closed by giving the command:

ISOSYMBOL CLOSE

This will overwrite an existing file.

Note: User double precision floating point representation for numbers is now used; previously single precision was used. Double precision provides increased accuracy in floating point numbers from six significant digits to 8.

Symbol files written by single precision releases of Draft cannot be re-opened for modification in double precision releases. Such files must be regenerated from the symbol elements using the ISOSYMBOL command to create a new file in a double precision release of Draft.
