Programming in HP PPL 549
GETBITS Syntax: GETBITS(#integer)
Returns the number of bits used by integer, expressed in
the default base.
Example: GETBITS(#22122) returns #20h or 32
R→B Syntax: R→B(integer)
Converts a decimal integer (base 10) to an integer in the
default base.
Example: R→B(13) returns #1101b (if the default base is
binary) or #Dh (if the default base is hexadecimal).
SETBITS Syntax: SETBITS(#integer[m] [,bits])
Sets the number of bits to represent integer. Valid values
are in the range –64 to 65. If m or bits is omitted, the
default value is used.
Example: SETBITS(#1111b, 15) returns #1111:b15
SETBASE Syntax: SETBASE(#integer[m][c])
Displays integer expressed in base m in whatever base is
indicated by c, where c can be 1 (for binary), 2 (for
octal), or 3 (for hexadecimal). Parameter m can be b (for
binary), d (for decimal), o (for octal), or h (for
hexadecimal). If m is omitted, the input is assumed to be
in the default base. Likewise, if c is omitted, the output is
displayed in the default base.
Examples: SETBASE (#34o,1) returns #11100b while
SETBASE (#1101) returns #0h ((if the default base is
hexadecimal).
I/O
I/O commands are used for inputting data into a
program, and for outputting data from a program. They
allow users to interact with programs.
CHOOSE Syntax: CHOOSE(var, "title", "item1",
"item2",…,"itemn")
Displays a choose box with the title and containing the
choose items. If the user selects an object, the variable
whose name is provided will be updated to contain the
number of the selected object (an integer, 1, 2, 3, …) or
0 if the user taps .
