u63 user exit

The u63 user exit sets/clears privilege bits.

Syntax

result = oconv(value, ’u63’)
result = iconv(value, ’u63’)

Parameter(s)

`value`	The bit to be set or cleared. must be one of these:
	0	Entire table.
	-1	Inhibit (like break on/off, but works like a bit).
	-2	TCL restart.
	-3	Break/End restart.

Description

If iconv is used then the value is set. If oconv is used, then the value is cleared. The result is the value of the bit before it was changed, except when used with the value 0. In this case, the result is undefined.

This user exit is similar to the bitset and bitreset commands on some licensee platforms.

CAUTION:

If the TCL restart or the Break/End restart bits are set, and there is no account Proc (or macro), then an attempt to go to TCL or end can cause an infinite loop.
