SYMPTOMS
In the Microsoft Macro Assembler (MASM) versions 5.1 and 5.1a, the IRP (instruction repeat) directive has a single line limit of 120 characters. MASM version 6.0 has no limit. The code example below shows a macro with an IRP that has 125 characters. The result of this program with MASM 5.1 or 5.1a is an error message that states:

End of file encountered on input file

Number of open conditionals:14

End of file encountered on input file



CAUSE
This error occurs because the assembler is looking for a closing bracket (>), but the line is over the limit of 120 characters. As a result, the assembler accepts the rest of the code to be part of the IRP parameters. By shortening the final parameter to be within the limit (change TP$_EOS to TP), the bracket is read correctly and the remainder of the program is assembled with no errors.



STATUS
Microsoft has confirmed this to be a problem in MASM versions 5.1 and 5.1a. This problem was corrected in MASM version 6.0.



MORE INFORMATION
Note: In this example, the IRP argument list is stated in three lines; however, it should be all on the same line to cause the error. The 120-character limit is only on the same line. A workaround is to continue the argument on the next line as seen below.

Sample Code
; Assemble options needed: none

$tran  macro   keyword irpc TP$_DUMMY, ifidn <&TP$_DUMMY>,  irp TP$_DUMMY2,  %out TP$_DUMMY2 endm endif endm endm

$tran    if_anything_cmd end
