Out of the box, the Casio FX-850P/FX-880P supports ten BASIC programs P0 to P9 and one MEMO databank. Extensive
research on the internals led to the insight that the pocket computer is capable of handling more than
10 programs, which can easily be accessed using the scientific library function. These programs can be
created and managed using PGM-PLUS. Aditionally, PGM-PLUS allows to create more than one MEMO databank.
The program has several modes offering different sets of functions:
Mode | Funktions | When active |
---|---|---|
RUN | Selecting of programs and databanks Initialization of LIB table |
Casio's CAL mode (MODE 0), Casio's BASIC mode des Casio (MODE 1), if a system password
is active (using the PASS command). |
EDIT | Selecting and management of programs and databanks Initialization of LIB table |
BASIC mode (MODE 1) without password |
DBS | Select databank DBS and RETURN | If variable DBS is nonzero |
DEL | Delete mode | Only active during deletion of programs |
Programs are identified by names of 8 chars in the Casio's builtin program tables. The most common are
"P0" to "P9", but also the four digit numbers of scientific library programs are such names. In PGM-PLUS each program
can be assigned a name, which should be unique. After PGM-PLUS has once been started after power up of the
Casio pocketcomputer, all programs may be started using the LIB
key, e.g. program P0 using "P0 LIB
",
program MEMOMAS using "MEMOMAS LIB
" -- exactly as for the scientific library programs.
As the Casio has two program tables internally, the scientific library programs can still be accessed as
usual. It's also possible to use program names within BASIC instructions, e.g. GOTO "LIB0:1000"
to jump to library program 1000 (memory calculator), or GOTO "LIB1:MEMOMAS"
to jump to MEMOMAS residing
in the RAM.
Note:As the pointers to the program tables are reset on each power on, PGM-PLUS has to be started once
to enable these extended functions.
