[Basic & Applied Instruction]
Function and operation explanation
1. 16-bit operation (SCL/SCLP)
The input value of the device specified by is processed by scaling for the specified conversion
characteristics, and stored to a device number specified by . Conversion for scaling is executed based
on the data table stored in a device specified in and later.
If the output data is not an integer, however, the number in the first decimal place is rounded.
→ For the method to set the conversion table for scaling, refer to the next page.

2. 32-bit operation (DSCL/DSCLP)
The input value specified by is processed by scaling for the specified conversion table, and stored to a
device number specified in . Conversion for scaling is executed based on the data table stored in a
device specified in and later.
If the output data is not an integer, however, the number in the first decimal place is rounded.
