You can display the attributes of a variable using the Attribute (ATTR) debug command. The attributes are the size (in bytes) and type of the variable.
The following is an example using the ATTR debug command.
CL declaration: DCL VAR(&CHAR2) TYPE(*CHAR) LEN(10) Debug command: ATTR &CHAR2 Result: TYPE = FIXED LENGTH STRING, LENGTH = 10 BYTES CL declaration: DCL VAR(&DEC) TYPE(*DEC) LEN(3 1) Debug command: ATTR &DEC Result: TYPE = PACKED(3,1), LENGTH = 2 BYTES
