32 Reference Filename: LMARFC02.DOC Project: Template: MSGRIDA1.DOT Author: Mike Eddy Last Saved By: Launi Lockard Revision #: 24 Page: 32 of 12 Printed: 10/02/00 04:14 PM ELSEIFDEF, ELSEIFDIF, ELSEIFDIFI, ELSEIFE, ELSEIFIDN, ELSEIFIDNI, ELSEIFNB, and ELSEIFNDEF. Optionally, assembles elsestatements if the previous expression is false. Note that the expressions are evaluated at assembly time. IF2 expression IF block is evaluated on every assembly pass if OPTION:SETIF2 is TRUE. See IF for complete syntax. IFB textitem Grants assembly if textitem is blank. See IF for complete syntax. IFDEF name Grants assembly if name is a previously defined label, variable, or symbol. See IF for complete syntax. IFDIF[[I]] textitem1, textitem2 Grants assembly if the text items are different. If I is given, the comparison is case insensitive. See IF for complete syntax. IFE expression Grants assembly if expression is false (0). See IF for complete syntax. IFIDN[[I]] textitem1, textitem2 Grants assembly if the text items are identical. If I is given, the comparison is case insensitive. See IF for complete syntax. IFNB textitem Grants assembly if textitem is not blank. See IF for complete syntax. IFNDEF name Grants assembly if name has not been defined. See IF for complete syntax. INCLUDE filename Inserts source code from the source file given by filename into the current source file during assembly. The filename must be enclosed in angle brackets if it includes a backslash, semicolon, greater-than symbol, less-than symbol, single quotation mark, or double quotation mark. INCLUDELIB libraryname Informs the linker that the current module should be linked with libraryname. The libraryname must be enclosed in angle brackets if it includes a backslash, semicolon, greater-than symbol, less-than symbol, single quotation mark, or double quotation mark. name INSTR [[position,]] textitem1, textitem2 Finds the first occurrence of textitem2 in textitem1. The starting position is optional. Each text item can be a literal string, a constant preceded by a %, or the string returned by a macro function.
