UNSPEC pseudovariable

The UNSPEC pseudovariable assigns a bit value directly to x; that is, without conversion. The bit value is padded, if necessary, on the right with '0'B to match the length of x, according to Table 63.

If x is a varying length string, its 2-byte prefix is included in the field to which the bit value is assigned. If x is an area, its control information is included in the receiving field.

The pseudovariable is subject to the rules for the UNSPEC built-in function described in UNSPEC.

Note:
Use of UNSPEC can affect the portability of your program.
