Equivalent commands

The SETUNI command, SET command, CUNUNIxx parmlib statements, and dynamic loading share some capabilities:

The SET command with the UNI=xx parameter is the same as the following SETUNI command:
```
SETUNI ADD,IMAGE=CUNIMGxx,DSNAME=TEST.CUNIMG.
```
The CUNUNIxx parmlib statements are the same as the SETUNI command parameters. For example, the following commands and statements are equivalent:
- MVS command: SETUNI ADD,FROM=37,TO=1200,TECH=RECLM
- CUNUNIxx parmlib statement: ADD,FROM=37,TO=1200,TECH=RECLM
Dynamic loading has the same effect as the equivalent SETUNI ADD command. For example, a call to the character conversion service might have the same effect as the following command:
```
SETUNI ADD,FROM=37,TO=1200,TECH=RECLM
```
