You didn't mention anything about which line to execute and which line to skip. Above while loop will execute all lines in batchJob file.
Pls give some sample of batchJob and some pattern/rule to decide when to execute a line and when not.

GLLINESTIPPLE(3G) OpenGL Manual GLLINESTIPPLE(3G)
NAME
glLineStipple - specify the line stipple pattern
C SPECIFICATION
void glLineStipple(GLint factor, GLushort pattern);
PARAMETERS
factor
Specifies a multiplier for each bit in the line stipple pattern. If factor is 3, for example, each bit in the pattern is used three
times before the next bit in the pattern is used. factor is clamped to the range [1, 256] and defaults to 1.
pattern
Specifies a 16-bit integer whose bit pattern determines which fragments of a line will be drawn when the line is rasterized. Bit zero
is used first; the default pattern is all 1's.
DESCRIPTION
Line stippling masks out certain fragments produced by rasterization; those fragments will not be drawn. The masking is achieved by using
three parameters: the 16-bit line stipple pattern pattern, the repeat count factor, and an integer stipple counter s.
Counter s is reset to 0 whenever glBegin() is called and before each line segment of a glBegin()(GL_LINES)/glEnd() sequence is generated.
It is incremented after each fragment of a unit width aliased line segment is generated or after each i fragments of an i width line
segment are generated. The i fragments associated with count s are masked out if
pattern bit s factor % 16
is 0, otherwise these fragments are sent to the frame buffer. Bit zero of pattern is the least significant bit.
Antialiased lines are treated as a sequence of 1 x width rectangles for purposes of stippling. Whether rectangle s is rasterized or not
depends on the fragment rule described for aliased lines, counting rectangles rather than groups of fragments.
To enable and disable line stippling, call glEnable() and glDisable() with argument GL_LINE_STIPPLE. When enabled, the line stipple pattern
is applied as described above. When disabled, it is as if the pattern were all 1's. Initially, line stippling is disabled.
ERRORS
GL_INVALID_OPERATION is generated if glLineStipple is executed between the execution of glBegin() and the corresponding execution of
glEnd().
ASSOCIATED GETS
glGet() with argument GL_LINE_STIPPLE_PATTERN
glGet() with argument GL_LINE_STIPPLE_REPEAT
