#UNFIX( symbol )
| #UNFIX | Unfixes a multi-valued symbol. |
| symbol | A multi-valued symbol. |
The #UNFIX statement unfiXEs the current value of the multi-valued symbol. If the unfiXEd symbol is referenced outside a #FOR loop structure, it has no value and you cannot reference any other symbols dependent upon the multi-valued symbol.
Example:
#SET(%OneFile,'HEADER') #! Put values into two User-defined symbols
#SET(%TwoFile,'DETAIL')
#FIX(%File,%OneFile) #! %File refers to 'HEADER'
#FOR(%File) #! %File iteratively refers to all file names
#FIX(%File,%TwoFile) #! %File refers to 'DETAIL'
#ENDFOR
#! %File refers to 'HEADER' again
#UNFIX(%File) #! %File refers to no spcific value
