what happens if you put the if qualifier in front of the comma and the options?

Thema: st: use of if command after commands with options
I wish to use the if command to select a subset for estimation purposes, but also use options for the main command. This doesn't seem to work, since stata thinks that "if" is a further option. For example, pca..., comp(6). If I follow this with "if x==1", it won't work because stata thinks that "x==1" is a further option for pca.
Comments please!
