Up to 255 words can be transferred at one time. For integer variables, however, only a maximum of 50 to 60
words can be transferred at one time. The following restrictions apply:
• A maximum of 255 characters can be written in one line.
• One variable must correspond to each word for integer variables.
Example: H format
1000 PC READ "59H4";
19 characters
Up to 79 variables using 3 characters per variable (236 ÷ 3 = 79) can be written. Therefore, a maximum of 59
words can be transferred at one time.

Meaning
Two ×m characters from the
beginning of 1 character
variable are converted into
ASCII data (2 characters
correspond to 1 word), and is
stored in the leftmost/rightmost
byte position in each word
specified by n.
n = 1: Rightmost byte (leftmost
byte is 00
)
hex
n = 2: Leftmost byte (rightmost
byte is 00
)
hex
n = 3: Leftmost and rightmost
bytes
Data of n array variables is
converted to a data format
specified by X (any of BCD,
hexadecimal, octal, or bit) and
stored to each of m words.
Character string arrays cannot
be used as variables.
→ J = 4
PC READ "I1"; J
→ J = 34
PC READ "I2"; J
→ J = 234
PC READ "I3"; J
→ J = 1234
PC READ "I4"; J
PC READ "I1"; A$ → A$ = "4"
PC READ "I2"; A$ → A$ = "34"
PC READ "I3"; A$ → A$ = "234"
PC READ "I4"; A$ → A$ = "1234"
PC READ "2I4"; A$ → A$ = "12345678"
Appendix C
Example
2A3:
The first 4 characters in 1
character variable is converted
to ASCII data, and stored to the
leftmost and rightmost bytes of
each word for 2 words.
S2I2:
Data from 2 array variables is
converted to hexadecimal and
stored in each of 2 words.
