Hello:
When Holger speaks, I pay attention. I have the following line
of code for reading POST input from CGI as follows:
;=======================================
either tmp > 0
[
buffer: make string! (tmp + 10) ; allocate storage space
while [tmp > 0] ; and read
; I think Holger suggests this is not good:
[tmp: tmp - read-io system/ports/input buffer tmp]
return buffer
]
What would be a safe alternative, please?
TIA
-Tim
