The default font used by an ESL Application can be specified in the configuration file (typically EslConfig.ini).
DEFAULTFONT=Esl Mono
You can also specify the height and width of the default font:
FONTHEIGHT=20
FONTWIDTH=12
The default font specification is used by the ESL compiler, with the references stored in the Windows Easel Binary (.web) file. This facility can be used to build different versions of the same ESL Application, when the User Machines have different screen sizes and resolutions.
