GLDEPTHMASK(3G)GLDEPTHMASK(3G)NAME
glDepthMask - enable or disable writing into the depth buffer
C SPECIFICATION
void glDepthMask( GLboolean flag )
PARAMETERS
flag Specifies whether the depth buffer is enabled for writing. If flag is GL_FALSE, depth buffer writing is disabled. Otherwise, it is
enabled. Initially, depth buffer writing is enabled.
DESCRIPTION
glDepthMask specifies whether the depth buffer is enabled for writing. If flag is GL_FALSE, depth buffer writing is disabled. Otherwise,
it is enabled. Initially, depth buffer writing is enabled.
ERRORS
GL_INVALID_OPERATION is generated if glDepthMask is executed between the execution of glBegin and the corresponding execution of glEnd.
ASSOCIATED GETS
glGet with argument GL_DEPTH_WRITEMASK

glIndexMask - control the writing of individual bits in the color index buffers
C SPECIFICATION
void glIndexMask( GLuint mask )
PARAMETERS
mask Specifies a bit mask to enable and disable the writing of individual bits in the color index buffers. Initially, the mask is all
1's.
DESCRIPTION
glIndexMask controls the writing of individual bits in the color index buffers. The least significant n bits of mask, where n is the num-
ber of bits in a color index buffer, specify a mask. Where a 1 (one) appears in the mask, it's possible to write to the corresponding bit
in the color index buffer (or buffers). Where a 0 (zero) appears, the corresponding bit is write-protected.
This mask is used only in color index mode, and it affects only the buffers currently selected for writing (see glDrawBuffer). Initially,
all bits are enabled for writing.
ERRORS
GL_INVALID_OPERATION is generated if glIndexMask is executed between the execution of glBegin and the corresponding execution of glEnd.
ASSOCIATED GETS
glGet with argument GL_INDEX_WRITEMASK

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
