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:
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
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
;Assemble options needed: none
.model small
; .model small, c ; This line will permit assembly.
.code
myadd PROC arg1:word, arg2:word
LES bx, arg1
LES dx, arg2
RET
myadd ENDP
END
