Pack Ramp/Soak Data (PACKRS)
The Pack Ramp/Soak Data statement moves one or more steps of the ramp/soak profile
for a given loop to or from a table. PACKRS is primarily intended to make the ramp/soak
profiles accessible to an operator interface and to provide a method for dynamic ramp/soak
profiling.

To/From Table - specifies whether you are writing data to or from the table.
Table Address - specifies the address of the table, to or from which data are
moved Valid descriptors are integer addresses (addresses containing an integer
value such as V100, V100(2), or WX77) if reading from the table, or writeable integer addresses (writeable addresses containing an integer value such as V101 or
WY11) if writing to the table.
Loop Number - specifies the loop number whose ramp/soak profile is involved
in the pack operation. Valid descriptors are integer addresses or values (any integer
value or address containing an integer value such as V100, V100(2), or WX77).
Number of Steps - specifies the number of ramp/soak steps to pack. Valid descriptors are integer addresses or values (any integer value or address containing an
integer value such as V100, V100(2), or WX77).
Starting Step - specifies the starting step in the ramp/soak profile at which the
pack operation will begin. Valid descriptors are integer addresses or values (any integer value or address containing an integer value such as V100, V100(2), or
WX77).
PACKRS Operation
The number of steps in a ramp/soak profile is established when it is programmed using the
Ramp/Soak Editor. The PACKRS instruction cannot expand or shorten the ramp/soak profile for a given loop. This instruction can only read or modify existing steps in a preexisting
profile. PACKRS instructions that specify operations on non-existent profile steps are invalid, and the execution of this instruction terminates.
