The DEFSNG statement defines all designated undefined variables AS SINGLE variables.

Syntax: DEFSNG firstletters

  • The variable first letters can be from A-Z or any other range.
  • You can also use commas for specific untyped variable first letters.
  • Variables DIMensioned as another variable type or that use type suffixes are not defined otherwise.
  • Qbasic's IDE may add DEFSNG before any new SUB or Function also(you can change or remove them if needed).
  • DEFSNG is normally the Qbasic default assignment for undefined variables anyhow.

Example: DEFSNG A-D, S
