newRPL: [UPDATED April 27-2017] Firmware for testing available for download

[Guenter Schink]

A very interesting list of SD-commands

Code:

SDNEXTFILE
SDOPENDIR
SDEOF
SDFILESIZE
SDTELL
SDSEEKCUR
SDSEEKEND
SDSEEKSTA
SDREADLINE
SDWRITETEXT
SDREADTEXT
SDCLOSE
SDOPENMOD
SDOPENAPP
SDOPENWR
SDOPENEND
SDPGDIR
SDMKDIR
SDCHDIR
SDRCL
SDSTO
SDSETPART
SDRESET

Look at this glitch
"This is some text" 'test' SDSTO
'test' will be turned into 'TEST' on the sdcard, which is o.k. as FAT doesn't distinguish between capital and lower characters.
BUT the command 'test' SDRCL will result in an error message "File not found". 'TEST' SDRCL works of course.

Next step: "another text" 'test' SDSTO will create a file "test;" which then is not accessible from the calculator. Now I change that name on the sdcard to 'test1' and SDRCL will work correctly
