Summary:
A program which uses the .MODEL directive and has a procedure which
receives arguments, will not assemble correctly if a language is not
specified. Under Microsoft Macro Assembler (MASM) versions 5.0, 5.1,
and 5.1a, the language is specified with the .MODEL directive and the
following errors will be produced the language is omitted:
A2022: Operand must be type specifier
A2009: Symbol not defined: 'symbol'
Under MASM 6.0, 6.0a, and 6.0b, the language can be specified as part
of the PROC syntax, with the .MODEL directive, with OPTION LANG, or
with switches /Gc or /Gd. The following errors will be produced if
the language is not specified
A2119: language type must be specified
A2006: undefined symbol: 'symbol'
The "Microsoft Macro Assembler Programmer's Guide" does not
indicate that the language parameter is required in this case.
More Information:
The language parameter on the .MODEL directive enables the PROC
extensions, changes the scope of code labels within procedures, and
may affect naming. When the language parameter is left off, the PROC
directive will only accept a NEAR or FAR specifier.
The following sample program illustrates the situation:
Sample Code
