35. Saving memory ~~~~~~~~~~~~~ When you are writing very large programs, or ones that need a lot of variable space, every byte can count to squeeze as much as possible into memory. All BASIC keywords are 'tokenised' into just one byte each, so "RESTORE" only occupies the same amount of memory as "TO", ie one byte. However, this is not true of the MOS 'star' commands. Thus *O. occupies 3 bytes, whereas *OPT occupies 4, and so on. You can abbreviate words like *KEY, *DELETE etc also. However, it is wise not to abbreviate *DISC or *TAPE, as this does not not work on all versions of Operating System.
