|Syntax||NEW_NAME old_name$, new_name$|
This command allows all keywords, variables, procedures, functions and device names to be renamed, whether they are in RAM or ROM (except device names, which must be RAM based), BASIC or machine code implementations. If a program is loaded when the command is issued, then all references in that program to the given name will also altered.
FORMAT can destroy a lot of data. To avoid a catastrophe when an alien, unknown BASIC program formats your hard disk for example, you could rename FORMAT:
NEW_NAME "FORMAT" TO "FORMAT_MEDIUM"
Note that you would need to issue this command before loading the program!
Creating algorithms is very easy and fast in SuperBASIC, especially if short variable names like i ,n, q1 are used. But even the author him/herself may have difficulty in understanding source code full of such meaningless names. The obvious solution: Rename them! - for example:
BASIC programs loaded in memory are amended completely and permanently - at once.
If you prefer to see all names in capital letters, run this short program:
100 adr=BASICP(32) 110 REPeat all_names 120 length=PEEK(adr) 130 IF NOT length THEN EXIT all_names 140 name$=PEEK$(adr+1,length) 150 NEW_NAME name$,UPPER$(name$) 160 adr=adr+length+1 170 END REPeat all_names
A name may be up to 255 characters long, and because it is only stored once (in the name table) and represented in a tokenised program by symbols pointing to the name table, the actual speed of operation will not be slowed down by using longer names.
It is possible to rename FORMAT to FORMAT! (for example) but FORMAT! is an illegal name, can no longer be called from BASIC and may crash some advanced implementations of SuperBASIC.
