Output 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

Filename is input either as a PML NAME (for example, ISOSYMBOL /%PMLUSER%\IsoFont.isl) or FILENAME (for example, ISOSYMBOL "%PDMSUSER\IsoFont.isl").

When spaces are present in the file path, the FILENAME format must be used, otherwise a Syntax Error is displayed.

The current symbol (for example, 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

The command overwrites 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 Draw 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 Draw.
