Using logical processing

–Non-numeric characters, such as currency symbols, positive and negative number designators, and alphabetic text may only precede, follow, or enclose the numeric character string.

Valid character strings would include the following if the appropriate VCODE table is specified:

‘$(1,500.00)’, ‘–1.500,00 DM’, and ‘kr–1.500,00’

–A numeric character string is evaluated as a negative number if a minus sign (–) either precedes or follows the string, or if the string is enclosed in a single set of parentheses.

Because of the simplified procedure used to determine negative numbers, the following occurrences make the string invalid:

•More than one opening parenthesis preceding the string

•More than one closing parenthesis following the string

•More than one minus sign.

–Leading zeros in the integer part and trailing zeros in the fractional part of a numeric character string, do not affect the value of the string. The “decimal point” character separates the integer part of a number from the fractional part. If a “decimal point” is not present, there is an implied decimal point at the end of an integer number.

The “thousands separator” is allowed within a numeric character string only if it is placed between groups of three digits going away from the “decimal point.” A “decimal point” or a “thousands separator” may appear repeatedly outside the numeric character string.

In VCODE0, the following are examples of valid numeric character strings: ‘50,000,’ ’0,000,50,’ ‘,,,42,’ ‘1.000,00,’ and ‘.......5.’

•The referenced TABLE command may not use the MASK parameter.

•When more than one character string constant is specified in the TABLE command, the following occurs:

–If the operator is EQ, the system tests the variable data against all the values in the TABLE CONSTANT statement. If any of the values are equal, the system returns a TRUE value.
