I wrote Summer '87 as my first paying job and did some 5.0/5.01 but probably haven't touched Clipper since 92 or 93?

I have been trying to remember some Clipper vocabulary to talk about another/different/completely new concept I'm working on but I can't remember the words.

Seems to me Clipper [due to RAM limitations] had this way of swapping pieces of code in and out and you could tell Clipper to leave certain code in RAM "all the time" and that was where you put your main stuff.

Anybody recall what I'm talking about or am I remembering something else entirely?

TIA

Something else entirely. Most languages have DLLs. DOS was going to limit anything except TSRs, which were usually not part of any code base.

Overlays? Am I thinking of overlays? I just happened upon an old InfoWorld ad for Clipper 5.0

Overlaying was job of linker (blinker, exospace), not of clipper. Here
the snippet of linker config file:

blinker cache XMS 50%
blinker overlay opsize 48
blinker overlay UMB OFF
output CHB

file CHB.OBJ
file f_RODCIS.OBJ
file f_CIS.OBJ
file f_SPLIT.OBJ
beginarea
file STD.OBJ
endarea
beginarea
file CHB321.OBJ
file CHB341.OBJ
file CHB351.OBJ
endarea
...

Yep - it was overlays. It had been so long that I had forgotten it was the linker that did the work & not Clipper itself. Thanks for your responses.

Clipper have 2 option, (the compiler):

1- variable for ram use documented in all manual of Clipper ( using clipper 5.2E are the best option in the DOS or DOSbox ).
DOS enviroment var: set clipper=xxx
for example use virtual memory to 64MB. or use 16MB of RAM with the EMS extension.

2- Compiler create overlap, for manager manualy at compiled, indicate the memory piece of module are static in ram or not... ( see compiler documentation ).

3- other option: DLC library creator simil to DLL but for clipper and C (3er party freeware kit)

4- change rtlink for blinker powerfull linker with memory extend system.

---------------------------

Or change to Harbour compiler :)

------------------------------------
for clipper resource:

I recall moving to Warplink for reasons I don't recall about 10 years
ago - I've just realised I've still got Clipper 5, Summer '87 and
Warplink on this computer together with the compiler/link files for an application I was working on.

I do recall it made things easier than the old BLINK(?)
