Define MASK Records to the SDT

The MASKREC keyword is required when adding a MASK record to the SDT Record.

To define a new MASK record to the SDT, enter the command:

TSS ADDTO(SDT) MASKREC(mask‑name) 
               DESCRIPT(descript‑name)
               MASKDATA(field‑definition)

MASKREC

Specifies a user‑defined record ID that must be unique for each MASK record. Valid names can contain alphabetic, numeric, national characters and Scandinavian vowels (hex codes, CO, DO, and 6A).

Size: 8 characters

DESCRIPT

Designates an optional user‑description field that is used as a logical name for this record. If the description field contains blanks, enclose it in single quotes.

Size: 32 character

MASKDATA

Contains the layout of the field to be masked. You can specify up to five fields on each MASKDATA keyword. Each field‑definition operand consists of five sub‑fields:

• fld‑name—Specifies an up to 24‑character field name unique to this MASK record. The name can consist of letters, digits, or national characters and can be qualified with periods (.), underscores (_), or hyphens (‑).
• type—Indicates the field type. Replace type with one of these values: CHAR (character), BIN (binary), PACKED, ZONED, HEX(hexadecimal).
• offset—Indicates an up to five‑digit offset value.
• length—Indicates an up to 44‑decimal value for length.
• mask—Indicates an up to 44‑character mask value. This value can contain letters, numbers, and special characters; however, the value must match the field type. The value specified for mask will appear in place of the actual value.

Example: define a DST MASK record

This example adds a MASKDATA field to the MASK record CRYPT1 that contains a salary field in character format called ADDR, masked with an asterisk (*), having an offset value of 50 and a length of 20 characters:

TSS ADDTO(SDT) MASKREC(CRYPT1) 
               MASKDATA(ADDR,CHAR,50,20,**)
