AMS 1.01 or higher | bascmd.h

void cmd_fnon (CESI IntList);

Executes TI-Basic 'FnOn' command.

If IntList points to END_TAG, cmd_fnon selects all 'Y=' functions that are defined for the current graphing mode (note that in split-screen two-graph mode, cmd_fnon only applies to the active graph). If IntList points to an integer item in the range from 1 to 99, cmd_fnon selects the specified 'Y=' function for the current graph mode, and repeats this task for all expressions on the expression stack below IntList, until END_TAG is reached. In 3D graphing mode, only one function at a time can be selected.

Uses: next_expression_index, gr_active, EQU_select, FindGrFunc
