Expressions in DIESEL (Direct Interpretively Evaluated String Expression Language) take strings as input and generate string results. You can use DIESEL in menu macros or to display text on the status line.
You can use the MODEMACRO system variable to display information on the status line.
You can use DIESEL string expressions in customization (CUI) files as an additional method of creating macros.
Status retrieval, computation, and display are performed by DIESEL functions. All functions have a limit of 10 parameters, including the function name itself. If this limit is exceeded, you get a DIESEL error message.
Generally, if you make a mistake in a DIESEL expression, what went wrong will be obvious. Depending on the nature of the error, DIESEL embeds an error indication in the output stream.
