numerical expression positions

Numerical expression positions are read positions in which numerical data objects, arithmetical expressions, and predefined functions, or functional methods and method chains, whose return value has a numerical data type, can be specified. The following numerical expression positions exist:

• Arguments of functions

• Numerical arguments of string functions

• Numeric arguments of extremum functions

• Counters and positions:

• Operand n in the statement
  DO n TIMES

• Operand sec in the statement
  WAIT UP TO sec SECONDS

• Operand num in the statement
  SHIFT ... BY num PLACES

• Operands bitpos and val in the statement
  SET BIT bitpos ... TO val.

• Operand bitpos in the statement
  GET BIT bitpos ....

• Position specifications in statements FIND and REPLACE:

• Operands off and len in the statements
  FIND ... IN SECTION ... OF
REPLACE ... IN SECTION ... OF

• Operands lin1, off1, lin2 and off2 in the statements
  FIND ... IN TABLE ... FROM lin1 OFFSET off1 TO lin2 OFFSET off2 ...
REPLACE  ... IN TABLE ... FROM lin1 OFFSET off1 TO lin2 OFFSET off2 ...

• Operands off and len in the statement
  REPLACE SECTION OFFSET off LENGTH len OF ...

• Specification of the row number idx with reference to a table index during access to an internal table in:

• READ TABLE itab INDEX idx ...

• LOOP AT itab ...FROM idx1 TO idx2 ...

• INSERT itab ... INDEX idx ...

• INSERT LINES OF jtab FROM idx1 TO idx2  ...

• APPEND LINES OF jtab FROM idx1 TO idx2  ...

• MODIFY itab INDEX idx  ...

• DELETE itab INDEX idx  ...

• DELETE itab FROM idx1 TO idx2 ...
