The following is a re-send of my earlier cry for help.  I received two replies
suggesting use of the STACK command prior to loading AmigaBASIC.  Tried both 
of those and got same result *OUT OF HEAP SPACE*.

There appears to be a tendancy of the members of this BBS to ignore questions
from the non-proficient user.  I certainly hope this is a mis-conception on
my part as I do not think any of the experts got to be experts with out some
one helping them when they were less than proficient.

<1.	Glad to see that I am not the only one with *dumb* questions.  We are 
<relatively new AMIGA owners at the home owner/user level.  As yet we have not 
<been able to acquire the necessary tech manuals so these questions may seem
<trivial to those who have access to them.
<
<2.	Additional handicap - We have only 256k.  Obviously 512 is needed to
<utilize much of the potential of the AMIGA and we will upgrade as budget 
<permits.
<
<3.	The first problem encountered is with AmigaBASIC (MicroSoft V1.1) and
<its memory management.  Opening Basic by double clicking it from the Extras
<disk yields two messages in the immediate window. 1 - 40xxx bytes storage
<available to system, and 2 - 14xxx bytes available to Basic.  Using the clear
<command I can re-allocate the 14k between the Basic Data and the Basic Stack.
<However I do not find any way to re-allocate more of the 40k to Basic.  Am I
<missing something fundamental here??
<
<4.	The second problem stems from trying to cure the first.  I edited the
<Startup-Sequence to preclude loading of Workbench, leaving the system under
<DOS.  My hope was that without Workbench, Basic would grab a major portion of
<the additional unused core.  Trying to load Basic directly under DOS resulted
<in much thrashing that culminated in the dreaded *Red Box* with the message
<OUT OF HEAP SPACE -PRESS LEFT MOUSE BUTTON TO CONTINUE.  This promptly returned
<to DOS.  When Workbench is loaded and a CLI window opened I can load Basic just
<fine, albeit it has only 13k of system storage available.  What does Workbench
<do to manage the HEAP allocation and how can I duplicate it or get around it??
<
<5.	Can someone clarify the use of the terms STACK, HEAP, and PILE?  Every
<time I think I understand the distinctions I read something that un-clarifies
<it for me.
<
<6.	If any of these problems are the result of my stupidity don't feel too
<bad about pointing it out.  I have not seen evidence of many faint-hearted
<members on this BB.
