Conditional Processing

The !IF ... !THEN ... !IFEND syntax is used for conditional processing inside a macro. Additional conditions can be expressed with !IF !ELSE or !ELSE. 

define !export(type = !tokens(1))
  !IF (!type !EQ "xlsx") !THEN
    save translate /outfile="export.xlsx" /type=xlsx /version=12 /map /replace /fieldnames /cells=values.
  !ELSE !IF (!type !EQ "dta") !THEN
    save translate /outfile="export.dta" /type=stata /version=8 /edition=se /map /replace.
  !ELSE
    save outfile="export.sav".
  !IFEND
!enddefine

Inside the !IF construct, string literals can be left unquoted. This comes with the unexpected side-effect of case-sensitivity.
