inlist

[ashar ata]

does inlist work both of the following ways?

the first one searching fro values 91, 92 and 93 in the variable px1

replace x=1   if inlist(px1, 91, 92, 93)

the second one searching for value 91 in varaibles px1, px2, px3

replace x=1   if inlist(91, px1,  px2,  px3,  px4)

Thanks

Yes. Note that the second is equivalent to

replace x = 1 if 91 == px1 | 91 == px2 | 91 == px3 | 91 == px4

which is equivalent to

replace x = 1 if px1 == 91  | px2 == 91| px3 == 91 | px4 == 91 

as if x == y then necessarily y == x.

It took me some time to see that the second form can be as useful as the first, and it's mathematical training to write one way (variable first, constant second) rather than the other that got in the way.
