13.5.19 Record Operators

• the ‘~’ operator
  • - integer ‘~’record

  Is the size (item count) of the operand. Same as the ‘r_size’ function.

• the ‘=’ assignment operator
  • - record (record ‘=’ record)

  Is the right operand, sets the left operand as a reference of the right operand. Same as the ‘r_set’ function.

• the ‘[’‘]’ indexing operators
  • - object (record ‘[’ text ‘]’)
  • - object (record ‘[’ data ‘]’)
  • - object (record ‘[’ object ‘]’)

  Are the data in the position indicated by the second operand in the record indicated by the first operand. Same as the ‘r_query’, ‘rc_query’ and ‘ro_query’ functions.

• the ‘[’‘]’‘=’ assignment operators
  • - type (record ‘[’ text ‘]’ ‘=’ type)
  • - object (record ‘[’ text ‘]’ ‘=’ any)
  • - object (record ‘[’ object ‘]’ ‘=’ any)

  Are the data in the position indicated by the second operand in the record indicated by the first operand, after it was set or replaced by the third operand. Same as the r_c_*, ‘r_case’ and ‘ro_case’ functions.

• the ‘[’‘]’‘+=’ addition assignment operators
  • - type (record ‘[’ text ‘]’ ‘+=’ type)

  Is the data in the position indicated by the second operand in the record indicated by the first operand, after it was added the third operand. If the record was mapping the position, the data was of the <type> data type. If it wasn’t, the data in the position is set as the third operand. Same as the ‘rn_a_*’ functions. Type is numeric.

• the ‘[’‘]’‘-=’ addition assignment operators
  • - type (record ‘[’ text ‘]’ ‘-=’ type)

  Is the data in the position indicated by the second operand in the record indicated by the first operand, after it was subtracted the third operand. If the record was mapping the position, the data was of the <type> data type. If it wasn’t, the data in the position is set as the negative of the third operand. Same as the ‘rn_s_*’ functions. Type is numeric.

• the ‘?’‘:’ selection operator
  • - record (integer ‘?’ record ‘:’ record)

  Is the second operand if the first is not zero, the third operand otherwise.

  Asssociates right to left.
