【 In lihm (Miming)'s post it was mentioned: 】
: Programs need to be compiled from the command line, with lots of switches, options, parameters, etc.
: So a compile or link command often exceeds the command-line length limit, resulting in
: the error arg list too lang.
: How can this be solved?
Under DOS the command line generally can't exceed 127 characters.
It seems MS C or MS Fortran had software that could raise this limit to 4096?
But I've never used this kind of thing.
Another method is to set environment variables, like tmp=, include=, and so on.
There are also ones that set pseudo-instructions (MASM does this), putting the parameter settings directly into the source program.
But neither pseudo-instructions nor environment variables have any unified standard,
you have to analyze each specific software case by case
