My computer has 512 Mbytes of RAM. How come TASM runs out of memory?
Prior to version 3.2, TASM was an old-fashioned program confined to the 640 Kbyte memory space provided by DOS. If you are running out of memory and you are using a version early than 3.2 you should upgrade and see if it eliminates the problem. Even version 3.2 has some inherent limits, however. There are fixed limits for the maximum number of labels and macros (see the TASM User’s Manual).
