Command,
Function
EOF
Returns -1 if the end of a sequential file is detected.
LOF
Returns the file size as the number of sectors.
LOC
Returns the current logical location within a file.
CVI
Converts a character string converted by the MKI$ function back to an integer.
Converts a character string converted by the MKS$ function back to a single
CVS
precision real number.
Converts a character string converted by the MKD$ function back to a double
CVD
precision real number.
Converts a character string, which was converted from an AD51H-BASIC single
precision real number by the MKS$ function, into the internal representation of a
CVSMBF
floating point real number (IEEE single-precision representation) used in QCPU,
AnA/AnU/QnACPU, AnUSCPUs.
Converts a character string, which was converted from an AD51H-BASIC double
CVDMBF
precision real number by the MKD$ function, into the internal representation of an
IEEE double precision number.
MKI$
Converts integer-type numbers to character strings.
MKS$
Converts single-precision type numbers to character strings.
MKD$
Converts double-precision type numbers to character strings.
Converts floating point real number data in internal representation (IEEE single-
MKSMBF$
precision representation) used in QCPU, AnA/AnU/QnACPU, AnUSCPUs into a
character string that can be changed into a numeric by the CVS function.
Converts IEEE double-precision data in internal representation into a character
MKDMBF$
string that can be changed into a numeric by the CVD function.
DEF FN

REM
Provides comments (remarks) in the program.
Sets variables, etc. used for transition to the program to be executed by the CHAIN
COMMON
instruction.
DATA
Specifies numeric values or character strings to be read by the READ instruction.
READ
Reads values defined by the DATA instruction and assigns them to variables.
Specifies the first line number of the DATA instruction data that are to be read by
RESTORE
READ.
LET
Assigns the expression value to a variable.
SWAP
Swaps the values of two variables.
ZMOVE
Transfers data between variables.
BSWAP
Swaps two values in byte units.
MID$ (Part1)
