Example

See parameter_list.

Exceptions

Catchable Exceptions

CX_SY_PROGRAM_NOT_FOUND

• Cause: The specified program was not found.
  Runtime Error: LOAD_PROGRAM_NOT_FOUND
  
• Cause: The specified program cannot exist because the program name is longer than 40 characters.
  Runtime Error: PERFORM_PROGRAM_NAME_TOO_LONG
  

CX_SY_DYN_CALL_ILLEGAL_FORM

• Cause: The specified subroutine was not found.
  Runtime Error: PERFORM_NOT_FOUND
  
• Cause: The specified index was too small.
  Runtime Error: PERFORM_INDEX_0
  
• Cause: The specified index was negative.
  Runtime Error: PERFORM_INDEX_NEGATIVE
  
• Cause: The specified index was too large.
  Runtime Error: PERFORM_INDEX_TOO_LARGE
  

CX_SY_DYN_CALL_PARAM_MISSING

• Cause: The called FORM expects more parameters than were specified.
  Runtime Error: PERFORM_PARAMETER_MISSING
  

CX_SY_DYN_CALL_PARAM_NOT_FOUND

• Cause: More parameters were specified than expected by FORM.
  Runtime Error: PERFORM_TOO_MANY_PARAMETERS
  

CX_SY_DYN_CALL_ILLEGAL_TYPE

• Cause: In the parameter transfer using the addition STRUCTURE, the addressing offsets/> do not match in the current and target structures.
  Runtime Error: PERFORM_BASE_WRONG_ALIGNMENT
  
• Cause: The deep components contained in the current and target structures cannot be passed to each other. This error can only occur in parameter transfer using STRUCTURE.
  Runtime Error: PERFORM_CAST_DEEP_MISMATCH
  
• Cause: During the transfer of a generically defined type to the form, a type conflict occurred.
  Runtime Error: PERFORM_CONFLICT_GENERIC_TYPE
  
• Cause: The table type of the current parameter does not match the table type of the parameter defined in the form.
  Runtime Error: PERFORM_CONFLICT_TAB_TYPE
  
• Cause: The type of current parameter does not match the type of parameter defined in the form.
  Runtime Error: PERFORM_CONFLICT_TYPE
  
• Cause: The current parameter occupies less storage space than the target parameter defined in the form. This error occurs only with parameter specification using STRUCTURE.
  Runtime Error: PERFORM_PARAMETER_TOO_SHORT
  
• Cause: During parameter transfer with the addition STRUCTURE, the fragment views of the current and target parameters do not match. This error only occurs in Unicode programs in
  Runtime Error: PERFORM_CONFLICT_UC_STRUCT
  
• Cause:When the form is called, an internal table is expected as current parameter.
  Runtime Error: PERFORM_TABLE_REQUIRED
  
• Cause: A hash table was passed to a parameter defined using TABLES.
  Runtime Error: PERFORM_STD_TAB_REQUIRED
