The openFT commands supply return codes that you can query when using SDF-P. Each return code consists of a subcode1 (SC1), a subcode2 (SC2) and the maincode (MC).
Subcode1
Subcode1 represents the error class. It is a decimal number. The possible error classes are:
No error:
the value of subcode1 is 0.Syntax error:
the value of subcode1 is between 1 and 31, inclusive.Internal error (system error):
the value of subcode1 is 32.Errors not assigned to any other class:
the value of subcode1 is between 64 and 127, inclusive. If the value of subcode 1 is in this range, the maincode must be evaluated in order to ascertain the appropriate action.Command cannot be executed at this time:
the value of subcode1 is between 128 and 130, inclusive.
Subcode2
Subcode2 either contains information supplementary to that in subcode1 or is equal to 0.
Maincode
The maincode corresponds to the message key of the SYSOUT message. You can use the /HELP-MSG-INFORMATION command to fetch detailed information.
For the command return codes of the file transfer and file management commands refer to chapter “Command return codes for file transfer and file management”. The command return codes of the remaining commands are always located after the detailed description of the command. In each case, the corresponding section specifies which command return codes are possible and what their meaning is.
