If there are no units specified for the variable name, or the variable

This is restricted to hoc variable names of the style, “name”, or “classname.name”.Īpart from the circumstance that the string arg style must be used whenĮxecuted from Python, a benefit is that it can be used when an instanceĭoes not exist (no pointer to a variable of that type). If the first arg is a string, it is treated as the name of the variable. *units_on_flag: off in the nrn/lib/nrn.defaults file. The units display may be turned off with h.units(0) or by setting the Variables must be given units before retrieving a session that shows them Note that units are NOT saved in a session. L, diam, Ra, t, etc are built-in and units for membrane mechanism variablesĪre declared in the model description file. String (if it exists) along with the normal prompt string. When units are on (default on) value editor buttons display the units map () print ( 'can read/change length.val, diam.val' )
