Here's a revised description of how sqrtPARSE gets called:

On page 3 at $5848, it checks if the flag for sqrtPARSE is set. If it
isn't, then it jumps ahead to $5851 and continues as normal. Otherwise, it
calls $3105, which is equivalent to call pg. D,$598F. $598F pushes OP1 and
then checks if sqrtPARSE exists. If it doesn't, it pops OP1 and returns to
5851. If sqrtPARSE exists, it gets rid of the pushed OP1, pops hl 3 times,
and calls _exec_asm to run sqrtPARSE. After _exec_asm returns, it does an
alternate return, if one is installed - otherwise it jumps to pg. 3,$678e,
which calls routines off the OP stack.
