SPSS Macro Logic

SPSS macros offer the following options for logic.

Contents

  1. SPSS Macro Logic
    1. Operators
    2. Conditional Processing

Operators

The following logical operators are valid for logic control of SPSS macros.

Operator

!EQ, =

!NE, ~=

!GT, >

!GE, >=

!LT, <

!LE, <=

!OR, |

!AND, &

!NOT, ~

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.
