Upon processing of SH1, SPIDER will shift PIC001, put the shifted image into SHI001, and then perform procedure RT1. Procedure RT1 will rotate the shifted image, and put the rotated image in ROT001. SPIDER will then encounter the 'RE' operation, and return to procedure SH1 where it left off (i.e., it will process the 'MO' operation, and continue with processing SH1).
If procedure RT1 were called directly by the user in interactive mode, SPIDER will return to the interactive mode upon encountering the 'RE' command.]
