Operators that can be used in any expression

Use the operators defined in this section to write LangX COBOL expressions.

+

Addition

-

Subtraction or prefix minus

*

Multiplication

⁄

Division

⁄⁄

Remainder

||

Concatenation (non-arithmetic operands only)

(...)

Parenthesis to control the order of operation, specify the subscript of an array, or select a substring.

symbol(subscript,subscript,...)

Parenthesis to specify a subscript or index for an array. Note that commas are required between subscript or index values. Blanks alone are not acceptable.

symbol(substrstart:substrend)

Parenthesis to select a substring of the bytes from substrstart to substrend from a character variable.

symbol(substrstart::substrlen)

Parenthesis to select a substring of substrlen bytes beginning at substrstart from a character variable.

For an array of character strings, these forms can be combined by using symbol(subscript,substrstart:substrend), or symbol(subscript,substrstart::substrlen).

LENGTH OF

Returns the length of a symbol. For example, LENGTH OF ABC returns the length of the symbol ABC.
