OMI - Set $Extract

Draft MDC Standard

☞

5.4.6 Set extract

(Operation type 12) This operation assigns a value to 1 or more contiguous character positions of a global variable’s value. If the variable does not already exist, the operation creates the variable with a value equal to the empty string before assigning the value. ANSI/MDC X11.1, 8.2.22 describes the semantics.

The first 3 fields of this request are identical to those of the set request in 5.4.4. These additional fields follow the first 3:

  1. Start position: <LI> the first position where the value is to be assigned.
  2. End position: <LI> the last position where the value is to be assigned. When assigning a single character position, this field shall equal the start position field.

The set extract response consists of a header only, indicating whether an error occurred during the operation.
