void cmd_cyclepic (CESI PicNamePrefix, CESI n, CESI wait, CESI cycles, CESI direction);

Executes TI-Basic 'CyclePic' command.

cmd_cyclepic implements the TI-Basic CyclePic command, which displays the Graph Screen and then displays a series of pictures (a slide show) on it in a cycle. The PicNamePrefix parameter should point to a string item on the expression stack (more precise, to its STR_TAG), and n should point to an integer item which determines the total number of pictures.
The names of the TI-Basic PIC variables which contain the picture data will be derived from PicNamePrefix and n. For example, if PicNamePrefix points to "pic" and n points to 5, the picture data will be picked from TI-Basic PIC variables called "pic1", "pic2", "pic3", "pic4" and "pic5".
The wait parameter should point to an integer or floating point item which determines the time between pictures. cycles should point to an integer item which determines the number of times to cycle through the pictures. direction should point to an integer item containing 1 or -1. If it is 1, the pictures will be displayed in a normal loop, and if it is -1, the loop will run in both directions.
Note: The TI-Basic command CyclePic is implemented to allow making simple animations in the TI-Basic. Although this function principally may be used in C to accomplish the same task, the usage of it is tedious and there are much better ways for doing this in C which are also independent of the Graph Screen. Take a look at the functions from graph.h, wingraph.h, and sprites.h.
