If it is always the first four characters in the workstation name that you need to check then this should do the trick.
 Code:
Select
	Case Left(@WKSTA, 4) = "ps12"
		Use g: '\\ps12-fs1\apps'
		Use r: '\\ps12-fs1\resources'
	Case Left(@WKSTA, 4) = "ps13"
		Use g: '\\ps13-fs1\apps'
		Use r: '\\ps13-fs1\resources'
EndSelect
