ELSEIF Assembler Directive

Abbreviation

None.

Arguments

ELSEIF expression

Default

None.

µVision

None.

Description

The ELSEIF directive begins an alternate block after an IF or ELSEIF directive. The ELSEIF block is assembled only if the specified expression is evaluated and the value is non-zero (TRUE). If the expression is zero (FALSE), the ELSEIF block is not assembled and subsequent blocks of the IF-ELSE-ENDIF construct are evaluated.

ELSEIF blocks are terminated by an ELSEIF, ELSE, or ENDIF directive.

Note

  • The specified expression may contain only those symbols defined using the SET and RESET directives. Symbols defined with the EQU and SET statements may not be used with the ELSEIF directive.
  • Do not confuse the ELSEIF directive with the ELSEIF statement. They are not equivalent and they may not be used with the same symbols.
  • This directive may not be specified on the command line. It must be specified in a source file.
