The code is very simple

procedure xxxx
lcProjdirx = getdir('C:', 'Project folder')

by here , the damage already done as getdir() returns a numeric '4' rather than the (char) name of the folder. If I include set step on before the prg line, it works. Maybe VFP corrupted ? as it has run normally for 3 years. Under VFP 7, its fine.

Assuming you check return value immediately on return from GetDir() (otherwise be sure you used a local variable) does adding an m. prefix help ? Would you show code portion.
