Data Label (DLBL)
The Data Label instruction marks the beginning of an
ASCII / numeric data area. DLBLs are programmed
after the End statement. A maximum of 64 (DL240 and
DL250–1/260) or 32 (DL230) DLBL instructions can be
used in a program. Multiple NCONs and ACONs can be
used in a DLBL area.
ASCII Constant (ACON)
The ASCII Constant instruction is used with the DLBL
instruction to store ASCII text for use with other
instructions. Two ASCII characters can be stored in an
ACON instruction. If only one character is stored in
an ACON, a leading space will be printed in the Fault
message.
Numerical Constant (NCON)
The Numerical Constant instruction is used with the
DLBL instruction to store the HEX ASCII equivalent of
numerical data for use with other instructions. Two digits
can be stored in an NCON instruction.
