41c271da (kx 2025-01-05 15:42:39 +0300 11) The \fBicvt()\fP function performs the operation of converting the value of the \fBa\fP variable
41c271da (kx 2025-01-05 15:42:39 +0300 12) into the value of a larger or smaller variable with preserving the value (and sign). The result
41c271da (kx 2025-01-05 15:42:39 +0300 13) is placed at \fBc\fP. The contents of the memory at address \fBa\fP are not changed, the previous
41c271da (kx 2025-01-05 15:42:39 +0300 14) memory contents at \fBc\fP are lost. The \fBnb_c\fP parameter determines the size of the operand
41c271da (kx 2025-01-05 15:42:39 +0300 15) (in bytes) located at address \fBc\fP, and the \fBnb_a\fP parameter determines the size of the
41c271da (kx 2025-01-05 15:42:39 +0300 16) operand (in bytes) located at the address \fBa\fP.

41c271da (kx 2025-01-05 15:42:39 +0300 18) The function affects the flags \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP.

41c271da (kx 2025-01-05 15:42:39 +0300 20) The flags \fBA\fP, \fBC\fP do not change (the previous value is retained). The \fBP\fP
41c271da (kx 2025-01-05 15:42:39 +0300 21) flag is set only when the size of the \fBc\fP operand is equal to one or two bytes
41c271da (kx 2025-01-05 15:42:39 +0300 22) (\fBnb\fP == 1 || \fBnb\fP == 2).
